Splice Instructions

Use this splice for Kevlar, T-900
and Spect-Set double braids to achieve maximum strength.

Step 1: Marking the Measurments
Place a single wrap of tape on the end of the rope, measure off two (2) fid lengths from the end and make a mark on the cover. This is mark "A". Form the eye and make a second mark opposite the first. This is mark "B". "A" to "B"= Eye Size.

Tie a slip knot approximately ten (10) fid lengths down from mark "B".

Step 2: Extract and Mark the Core
Extract the core at mark "B" by bending the rope sharply and carefully spreading the cover strands to expose the core. Then pry the core braid out by using the pointed end of the Uni-Fid.

Place a single wrap of tape on the end of the core and then, while holding the exposed core, slide the cover back as far as possible towards the knot. Then smooth the cover back over the core to the point of extraction. Smooth cover again until all slack is removed and mark the core where it comes out of the cover. This is mark "1". Again, slide the cover back towards the knot and measure one short fid section towards the knot from mark "1" and mark the core. This is mark "2". Measure 3 fid lengths towards the knot from mark "2" and mark the core. This is mark "3"

Step 3: Inserting the Core Into the Cover
Attach the fid to the end of the core. Insert the core into the cover at mark "A" around the radius of the eye and out of the cover at mark "B". The sections of the core exiting from the cover at mark "B" should pass through the same hole between the cover strands.

Pull the core through the cover until mark "1" on the core is aligned with mark "A" on the cover. Hold mark "1" and mark "A" together and smooth out the cover from mark "A" to mark "B" to remove all of the slack in the cover. After removing all of the cover slack, mark the core tail where it exits the cover at mark "B". This is mark "4".

Step 4: Burying the Core Tail
With the Uni-Fid still attached to the end of the core, insert the core tail into the core at mark "2" and out at mark "3". Pull the core tail through until mark "4" is aligned with mark "2". Pull out sufficient core tail from mark "3" and remove the fid.

Step 5: Tapering the Core Tail
Starting at the end of the core tail, count three (3) consecutive strands revolving either to the right or to the left and mark the third strand pair. Count another five (5) consecutive strands and mark a fifth pair. Continue counting and marking the fifth consecutive strand pair until a total of five (5) strand pairs have been marked.

Cut and remove the five marked pairs from the core tail. Remove any masking tape from the end of the core tail and bury the core tail into the body of the core by holding the marks "2" and "4" in alignment and smoothing out the core from mark "2" to mark "3".

Step 6: Bury the Core-to-Core Splice
Secure the slip knot to a fixed anchor point. Bury the exposed core-to-core splice up to mark "1" by:

1. Holding the core at the point where mark "2" and mark "4" coincide, placing tension on the rope and smoothing out the cover back over the core from the slip knot towards the eye.

2. As the cover approaches the point on the core where marks "2" and "4" coincide, it may be necessary to alternately pull some of the core back out of the cover and resmooth the cover over the exposed core in order to get the cover over marks "2" and "4" and up to mark "1" on the core.

Step 7: Finishing the Splice
After the exposed core has been buried back into the cover up to mark "1" on the core, smooth out the cover from mark "B" to mark "A" around the eye.

Put the rope and tail cover tail under tension and tape the end of the cover tail to the standing part of the rope. Using nylon whipping thread, tightly whip the cover tail for a length of 1 short fid from the base of the eye.
