 “FULL CIRCLE” SLIPS

REMOVABLE INSERTS

Full Circle Slip Inserts are available for Cavins “Advance” Spiders, Models

“B”, “C”, “C-HD”, “F”, and “G” 

The Cavins “Full Circle” Slips, (Type “FCR”) with removable inserts were designed to replace Full Circle Slips with integral teeth. The “FCR” Full Circle Slips surround the pipe 360 degrees and exert a uniform gripping power on the pipe to avoid deformation, bottle-necking, or crushing. A heavy-duty steel pin retains each insert securely in each slip body segment. The cotter key secures the retaining pin in place.

 THREE DISTINCT ADVANTAGES ARE REALIZED WITH THIS NEW DESIGN:

1. It eliminates the purchase of individual slips for every size of tubular goods.

2. The Slip Body is made of tough alloy steel for maximum strength while the Inserts are of case hardened steel for longer wear.

3. Since only a minimum of Slip Bodies are required to cover the range of tubular goods for each spider, the investment compares less than it would with the purchase of individual slips for each size pipe.
