What is Splice Eye Climbing Rope?

A splice eye climbing rope is a rope terminated in a splice eye shape. It keeps its shape indefinitely because of how it is developed. Besides, in these splices, the rope is untwisted or deconstructed at the rear, then interlaced or placed back inside the rope, thus establishing an “eye” or loop. 

Can You Splice a Climbing Rope?

Yes. Not all ropes are created equal, meaning they are not all the same. Several types of ropes are impossible to splice, and the spliced eye has to be stitched precisely using an industrial-grade sewing machine. 

All ropes with a solid build are in the “un-spliceable” category, together with ropes designed with a parallel core referred to as static lines. Usually, fixed lines feature no stretch and an almost impenetrable jacket; thus, they’re very challenging to splice. All the same, there are climbing ropes that can be spliced, though this depends on the material they’re made using. 

How Do You Splice Climbing Rope Together?

A splice comes in handy when a surging thickness of the joined rope is acceptable. Again, it is made by unraveling the ends of the ropes to a specific length, uniting them, allowing their strands to overlap, then folding each alternatively above and beneath other strands several times. 

How is a Splice Made?

Splices usually depend on the rope’s structure. Mostly, climbing ropes are made of textile, and they comprise threads or fine fibers which are intertwined to create strands. For instance, you first need to unravel the rope’s end into strands in a spliced eye. You will braid them again by following specific instructions after forming the eye. Plus, you can stitch each splice when you’re done, as this weaving will safeguard it against slipping. Besides, it is a sign of changes within the splice structure. 

How Do You Splice a Rope Step By Step?

Splicing a rope is quite a long process, and here’s how to go about it: Split your rope into three strings. Mostly, ropes constitute multiple strands typically attached at the rear using an adhesive or fastener. Cut the rope ends to separate them. Again, if your rope has more than three strings, try splitting the rope equally among the three strands. 

Seal the strands’ ends as this will hinder your rope from unraveling when working on it. Typically, you can seal most synthetic ropes by attaching the ends using fire. You can use a lighter and hold the flame to each strand’s end till they fuse. Also, you can use glue to secure the strands if you have natural fiber rope to hinder further unraveling. 

Next, use duct or electrical tape to cover your rope on the strands’ ends. Moreover, it strengthens and makes the rope stiffer, thus making it easier to go through gaps and loops. You will feed the strands in tandem with the primary portion of the rope to form an unbroken line. It is necessary that every strand be lengthy enough to tie across the rope’s width approximately five times. 

At the rear end of the length, the strands will go through the main rope though they’re still frayed; use a small piece of tape to cover the rope and hinder more strands from fraying. Nevertheless, if the strands are not long enough, it might be insufficient to move every strand through the rope, five times as required to make this splice best. 

The next thing is to determine the size of the spliced eye. Have the secured portion of the independent end strand move across the main rope where you need the splice tied. This loop created by the rope and the attached rear of the 3-strand end will determine the loop’s size. Consider the purpose of the rope since a big eye may be suitable for some tasks but not so much for others. 

How Do You Splice Two Ends of Rope Together?

Unravel each rope’s end at least 40 crowns and tie securely with twine to hinder ropes from further fraying. Take 26 extra crowns and tie a second knot. 

The braiding of these two ropes leads to matched strands and temporarily secures the matched pairs as close to their attaching point as possible. Remove the tape from one string, begin unraveling one strand, and switch it for a strand from the other side as you separate it. 

Once you have a complete turn of the substitute strand in place, tie the lashing that you’d undone. Then continue fraying and substituting the strand for at least 25 crowns to the second lashing piece secured to the rope previously.

Make an overhand knot to fasten the substitute strand to the replaced strand. Ensure to tie the knot in the strand twist’s right side. On the other hand, depending on the material, you might need to add extra temporary lashing through the knot. 

You will do the same thing as the previous steps but in the opposite direction. You will substitute one of the strands with another. It would help if you were careful when making the first substitution turns to ensure that there’s no extra slack between these strands at the fastening point. 

Make an overhand knot at the fastening point between the remaining strings. Nonetheless, it would be best to tie the knot in the same direction as a strand twist. 

Take away the lashing, and then tie every strand two times. These tucks have to be at a right angle to the twists’ direction over one strand and beneath the other strand. Again, haul them snugly for every pair of strands to guarantee the overhand knot is tight and secure. Now, tuck every strand two more times. 

Note: when you tie the overhand knot properly for the first tuck, the strand is supposed to move over the standing portion of the strand it is fastened to and then beneath the adjacent strand. 

Lastly, if you desire a tapered splice, cut every strand by eliminating 1/3 of the material and making an extra tuck for them. Next, eliminate an equal material amount and perform a second tie for every strand. Then cut the strand near the rope and use your hands to smoothen out the splice. 

How Do You Join Rope Together?

You can use either splice, knot, or bend two ropes to join them. When it comes to a bend, it is a knot that links two ropes together; thus, it is excellent for climbing. However, splicing is the best way to join ropes together. 

This is because a splice is stronger than a knot or bend. There are various types of rope splicing, including spliced eye, long, short, and end splice techniques. Depending on your situation, these splice methods could come in handy. On the other hand, the spliced eye technique is the best rope splicing method. 

Is a Splice Stronger than a Knot?

Yes, a splice is stronger than a knot. When compared to a knot, you can obviously see how strong a splice is. A knot decreases the braking power of a rope by not more than 50%. With the best fibers like Vectran and Dyneema, the decrease can go up to 80%. On the other hand, a spliced eye only decreases the breaking strength by approximately 15%, which is a huge difference. Besides, the pesky loose rope, which needs a secure knot, is integrated into the rope when splicing. 

Moreover, a splice is slender, which is quite handy when climbing. 

When is Spliced Eye Rope Needed for Climbing?

The splice eye is utilized to position a permanent loop on the rope’s end, typically attaching to a fixed point. Again, a spliced eye rope comes in handy in forming your rope across the thimble, which is utilized to shield the rope, particularly when it is to be fastened to a wire, chain, or shackle. 

Best Way to Protect Spliced Eye Climbing Rope?

It would be best not to use a climbing rope sporting two spliced eyes for safety purposes. Once you climb to this rope’s end in the direction of the free end when moving downhill, the splice may move. 

What’s more, ensure you keep a minimum distance of 5 meters from the free eye when climbing. Plus, make sure to check this eye frequently for thickening or shifts. 

What is the Difference Between a Splice and a Knot?

A rope splice is the creation of a semi-permanent attachment between two parts of a rope of two different ropes by partially unraveling and then braiding the strands. Splices come in handy in forming a stopper at the rope’s end to create an eye or loop or fastening two ropes together. 

Splices are more preferred than knots because though a knot usually lessens the breaking strength significantly, a splice can reach the ropes’ full strength. On the other hand, splicing usually leads to line thickening; if removed, it deforms the rope. 

Most rope splice types are utilized on 3-strand ropes, although some can be attained on 12-strand or more single-braided ropes and multiple double braids. However, a rope splice is stronger than a knot. 

How Do You Know When to Splice?        

Typically, a splice is used to join two ropes or two parts of the same rope or form a stopper at the line’s end. So, when you require joining two ropes or parts of the same rope, the best move is to splice it, compared to making a knot, as it is much stronger. 

What are Some of the Different Types of Splicing?

Here are the different types of splicing:

1. End or back splice

This is where the rope’s strands are spliced right back into the rope’s end without creating a loop. Usually, it is unitized to terminate the rope’s end to prevent unraveling. The rope’s end with the splice is almost double the thickness of the main rope. The end splice is not used with ropes made of plastic materials and nylon since the strands are fused using heat to hinder unraveling. 

2. An incomplete cut splice

Also known as cunt splice, this is almost the same as the spliced eye. Normally. It is used for loglines or other light lines where one splice usually unravels. Besides, it makes quite a strong knot. It is a joint of two different ropes, achieved by side-slicing the rear ends relatively apart to form an eye in the fastened rope, which remains locked when tightened. 

3. Splice eye 

This is a splice where the active part is spliced into the working end, creating a loop.

4. Ring splice

This is formed in the rope’s working end to a clew or ring. 

5. Chain splice

A chain splice is linked to the rope’s working end and a chain. 

6. Long splice

The long splice comes in handy in joining two ends of two ropes to create one rope length. This is quite different from most splices since it leads to a somewhat thicker splice than the rope that doesn’t feature a splice, though it gives up more strength than a short splice. You can achieve this by substituting two rope end strands with those from a different strand and removing some of the additional strands. This splice lets the rope fit through various pulleys, which comes in handy in different applications. 

7. Short splice

Used to join two rope ends, this splice leads to the spliced portion being two times as thick as the un-spliced part and has more significant strength than a long splice. Besides, the short splice keeps more rope strength than all knots. 

What are the Benefits of Using a Knotless Rope Rather than a Spliced Rope?

Using a knotless rope comes with the benefit of retaining 100% strength even when wet. These ropes hold together when rigging without pulleys or blocks. 

If You Have to Splice Rope, what Method is Best?

The spliced eye technique. This is because it is the best way to decrease a rope eyelet; thus, it is utilized when a rope needs to be fixed or attached to an object.
