Technical Details

I acquired my MR from Cesar Sandoval in 2011.

My MR is 286 mm. long, 92 mm. wide, 81 mm. thick, and weighs 724 g.

This is a collapsible grappling hook with three claws. The shaft is made from a roughly 80 mm. diameter, 223 mm. long piece of aluminum alloy, likely 7075. Most of the length is turned down to 25.8 mm. diameter, while the upper 60 mm. is milled out to form a spider for holding the arms. The spider supports three 6.4 mm. thick aluminum alloy (7075?) claws which freely pivot on 6.3 mm. pins. A second pin for each claw limits its movement. Each claw has a chisel end and 22 scallops on the underside, forming 21 teeth.

The MR has a rotating locking mechanism recessed into the top of the spider and secured by an Allen cap screw. Turning the latch mechanism 60° in either direction allows the arms to rotate freely, another 60° (again, in either direction) locks them in the open or closed position as desired. The latch mechanism does not support any load during use, it merely holds the claws open while the hook is thrown and closed while it is stored.

An aluminum alloy (7075?) shackle pivots at the base of the shaft on a press fit 7 mm. stainless steel pin.

There are no identifying marks on this device.

Comments

Warning: Don't trust your life to a grappling hook.

The MR Grappling Hook is a well-made execution of an excellent design. The hooks and teeth are not as wicked-looking as those on the Tactical & Rescue Gear Grabber, and with the arms opening farther, they may not grab as well on some surfaces; however, the relative performance of the two really does depend on what the surface is. In some cases, the MR holds better. One thing is certain: the mechanism on the MR is much easier to use. With minimal practice and some care to keep my fingers out of the way, I can open or close the MR in well under 1.0 seconds - most of which is waiting for the arms to fall into place.
