Class II ropes are made in whole or part from any of the following
high modulus bers: Dyneema
®
, Vectran
®
, Technora
®
, and Zylon
®
.
The eye splice is used to place a permanent loop in
the end of a rope, generally for attachment purposes
to a xed point. An eye is also used to form the rope
around a thimble, which is used to protect the rope,
especially when it is to be attached to a shackle, chain,
or wire rope.
This eye splice may be performed on new or used
rope. This is an all-purpose splice technique designed
for people who generally splice used rope as frequently
as new rope. By following the procedure below, the
splice can retain from 90% to 100% of average new
rope strength and in used rope up to the same proportion
of residual used rope strength.

step
Tape end of line to be spliced
and measure 1 tubular d length
(or 2 wire d lengths) from taped
end of line and make Mark 1.
From Mark 1 measure 2 tubular
d lengths (or 4 wire d lengths)
and make Mark 2. Now form size
of eye desired and make Mark 3.

step
From Mark 1, in the direction of the taped end of the line, mark every second right and
left strand* for 3 strands.** Pull every marked strand out of line and cut (tape at end can
cause resistance and may have to be removed in order to pull out cut strands.) Tapered
end will now have only 6 strands remaining (or 4 strands for an 8-strand braid.) Tape
tapered tail tightly to keep from unbraiding.
step
3
Measure 3-1/2 tubular d lengths from
Mark 3 (7 wire d lengths), make Mark
4. Insert d and tapered tail at Mark 3
and bring d out beyond Mark 4.
Pull d and tapered tail out.
Do not let the line twist.
*Some rope diameters may have pairs of strands in
right and left direction. In this case, treat the pairs of
strands as a single strand, marking and cutting both
in each direction as described above.
**Some very small diameter ropes may be 8-strand.
For an 8-strand construction, mark every 3rd left
and right strand for 2 strands.
