Technical Details

I acquired my Israeli Folding Anchor from Joseph Healy in 2011, after he obtained a couple from Israel.

This device is 145 mm. long, 51 mm. wide, 42 mm. thick, and weighs 688 g.

This device consists of a body milled from an aluminum extrusion and a pivoting arm formed from two aluminum bars connected by stainless steel pins. Each pin is 9.5 mm. in diameter and pinned in place with a 3 mm. cross pin at each end. One of the pins serves as an axle for the arm to pivot on. The arm has six 4.75 mm. hardened steel pins with conical points, three on each side. The body is milled from an L-shaped extrusion. It has six holes aligned with the six hardened pins, providing the relief needed for allowing the arm to close fully. The body also has an 18.9 mm. wide, 12.6 mm. high beveled oval hole as a connecting eye. Two threaded holes in the back hold a pin, spring, and set screw each. These interact with hidden depressions on the axle to mildly lock the arm in the open or closed positions. In the open position, the arm makes about an 84° angle with the body rather than a full 90°.

There are no identifying marks on this device.

Comments

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

I called this a grappling hook, but it looks like it was meant to be placed, not thrown. Joseph Healey acquired several of these on eBay, and sent me one. He wrote,

When the jaws are open (only to 87 degrees) the device reveals six incredibly hard and sharp steel points - from what I can tell these would basically only be used by tactical teams for rapping off the 90 degree tops of walls. The slightly less than 90 degree piece the rope would attach to causes the top pointed piece to want to dig in hard into whatever material the wall would be made of. From the feel of those points, they’d be just as comfortable sticking into concrete as wood. They’re also too damn heavy to be regular climbing gear. Beautifully made, however.

I doubt that I could improve on his words.
