Ergodyne Squids 3791 Sleever Bar Locking Collar with Tethering Attachment Point
Customize
The Ergodyne Squids 3791 Locking Collar with Tool Attachment Point retrofits connecting, sleever and wrecking bars to provide a reliable tool tether or holstering catchpoint. Slide the collar onto a straight‑shafted round or hex bar and tighten the dual set screws with the included hex key for secure installation. Constructed of galvanized steel, the collar is corrosion‑resistant for extreme jobsite environments and includes a swiveling connection point that reduces tangles; the swivel attachment can be removed when only a holstering collar is needed. Designed and tested to withstand defined weight limits, these collars are third‑party certified to ANSI/ISEA 121‑2018 with a 7 lb (3.2 kg) maximum working capacity. Ideal for iron/steel trades, construction, telecommunications, oil & gas, power generation, utilities, wind energy and manufacturing jobsites where dropped‑object prevention is required. Each unit includes one locking collar and one hex key.
