Wire Rope Grips
G-450
  • Each base has a Product Identification Code (PIC) for material traceability, the name CROSBY or"CG", and a size forged into it.
  • Sizes 1/8" through 3" have forged bases.
  • Entire Clip - Hot Dip Galvanised to resist corrosive and rusting action.
  • Only Genuine Crosby Clips have a Red U-BOLT for instant recognition.
  • All Clips are individually bagged or tagged with proper application instructions and warning information.
  • Clip sizes up through 1½" have rolled threads.
  • Crosby Clips,all sizes ¼" and larger, meet Federal Specification FF-C-450 TYPE 1 CLASS 1.

SS-450 Stainless Steel
  • Each base has a Product Identification Code (PIC) for material traceability, the name CROSBY or"CG", and a size forged into it.
  • Available 1/8" through 5/8"
  • Entire Clip is made from 316 Stainless Steel to resist corrosive and rusting action.
  • All components are Electro-Polished.
  • All Clips are individually bagged or tagged with proper application instructions and warning information.

G-429
  • Bolts are an integral part of the saddle. Nuts can be installed in such a way as to enable the operator to swing the wrench in a full arc for fast installation.
  • All sizes have forged steel saddles.
  • Entire Clip - Hot Dip Galvanised to resist corrosive and rusting action.
  • All Clips are individually bagged or tagged with proper application instructions and warning information.
  • Assembled with standard heavy hex nuts.


WARNING
  • Failure to read, understand, and follow these instructions may cause death or serious injury.
  • Read and understand these instructions before using clips.
  • Match wire rope end termination only as instructed.
  • Do not use with plastic coated wire rope.
  • 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 (see table 1).

Efficiency ratings for wire rope end terminations are based upon the catalogue breaking strength of the 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 sizes 1" through 3½" is 90%.

The number of clips shown (see table 1) is based upon using RRL or RLL wire rope, 6x19 or 6x37 Class, FC or IWRC;IPS or XIP. If Seale construction or similar large outer wire type construction in the 6x19 Class is to be used for sizes 1" 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, 8x19 Class, IPS, XIP, sizes 1½" and smaller; and to rotation-resistant RRL wire rope, 19x7 Class, IPS, XIP, sizes 1¾" and smaller.

For other classes of wire rope not mentioned above, we recommend contacting LIFTING & SAFETY SERVICES.

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 in 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 !) - exception G429. 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 as near the loop or thimble as possible, turn nuts on the second clip firmly, but do not tighten. Proceed to Step 3.

3.
When tree or more clips are required, space additional clips equally between first two - take up slack - tighten nuts on each U-Bolt evenly, alternating from one nut to the other until reaching recommended torque.


WIRE ROPE SPLICING PROCEDURES: (Using Crosby Clips)

Fig. 1
The preferred method of splicing two wire ropes together is to use interlocking turnback eyes with thimbles, using the recommended number of clips on each eye (See figure 1)

Fig. 2
An alternative method is to use twice the number of clips as used in a turnback termination. The rope ends are placed parallel to each other, overlapping by twice the turnback amount shown in Table 1. The minimum number of clips should be installed on each dead end (See Figure 2). Spacing, installation torque, and other instructions still apply.
Important
Apply first load to test the assembly. This load should be 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 show in the table, the amount of turnback should be increased proportionally.
* The tightening torque values shown are based upon the threads being clean, dry and free of lubrication.
