3.
When three or more clips are required, space additional clips equally
between first two - take up rope slack - tighten nuts on each U-Bolt evenly,
alternating from one nut to the other until reaching recommended torque.
4. If a pulley (Sheave) is used, in place of a
thimble add one additional clip. Clip spacing should be as shown.
5. WIRE ROPE SPLICING PROCEDURES:
The preferred method of splicing two wire ropes together is to use interlocking
turnback eyes with himbles, using the recommended number of clips on each
eye (See Figure 5). 
An alternate method is to use twice the number of clips as used for a
turnback termination. The rope ends are placed parallel to each other,
overlapping by twice the turnback amount shown in the application instructions.
The minimum number of clips should be installed on each dead end (See
Figure 6). Spacing, installation torque, and other instructions still
apply.
6. IMPORTANT
Apply first load to test the assembly. This load should be of equal or
greater weight than loads expected in use. Next, check and retighten nuts
to recommended torque.
In accordance with good rigging and maintenance practices, the wire rope
end termination should be inspected periodically for wear, abuse, and
general adequacy.

| If
a pulley (sheave) is used for turning back the wire rope, add one
additional clip. |
| If
a greater number of clips are used than shown in the table, the amount
of turnback should be increased proportionately. |
| *The
tightening torque values shown are based upon the threads being clean,
dry, and free of lubrication. |

|
Efficiency ratings for wire rope end terminations
are based upon the catalog breaking strength of wire rope. The efficiency
rating of a properly prepared loop or thimble eye termination for clip
sizes 1/8" through 7/8" is 80%, and for sizes 1" through
3-1/2" is 90%.
The number of clips shown (see Table 1 ) is based upon using RRL or RLL
wire rope, 6 x 19 or 6 x 37 Class, FC or IWRC; IPS or XIP, XXIP. If Seale
construction or similar large outer wire type construction in the 6 x
19 Class is to be used for sizes 1 inch and larger, add one additional
clip. If a pulley (sheave) is used for turning back the wire rope, add
one additional clip.
The number of clips shown also applies to rotation - resistant RRL wire
rope, 8 x 19 Class, IPS, XIP, XXIP, sizes 1-1/2 inch and smaller; and
to rotation-resistant RRL wire rope, 19 x 7 Class, IPS, XIP, XXIP sizes
1-3/4 inch and smaller.
For other classes of wire rope not mentioned above, we recommend contacting
Crosby Engineering at the address or telephone number on the back cover
to ensure the desired efficiency rating.
For elevator, personnel hoist, and scaffold applications, refer to ANSI
A17.1 and ANSI A10.4. These standards do not recommend U-Bolt style wire
rope clip terminations. The style wire rope termination used for any application
is the obligation of the user.
For OSHA (Construction) applications, see OSHA 1926.251.
1.
Refer to Table 1 in following these instructions. Turn back specified
amount of rope from thimble or loop. Apply first clip one base width from
dead end of rope. Apply U-Bolt over dead end of wire rope live
end rests in saddle (Never saddle a dead horse!) Tighten nuts evenly,
alternate from one nut to the other until reaching the recommended torque.
2.
When two clips are required, apply the second clip as near the loop or
thimble as possible. Tighten nuts evenly, alternating until reaching the
recommended torque. When more than two clips are required, apply the second
clip as near the loop or thimble as possible, turn nuts on second clip
firmly, but do not tighten. Proceed to Step 3.
