i responded earlier pointing to ladder snap; and for the application; think the non -locking is best.
i only recommended that for a saw holder per certain request. i believe something to hang ropes on too was mentioned.
i don't beleive the throat size of any ladder snap is right for lanyard either, even in locking style; there is a specification for that too! That aside i have an old WesSpur catalog (Carla @1-800-845-1213) that has a non-locking ladder snap in it. One time she was real sick and could bareley talk; was having bad day till i started cracking 1-900-Whis-Spur jox! Though i wood beleive that you could find it locally for other disciplines. Might even call Dr. Tobe for a special order.
JP's choice of snap for layard matches my own; i especially like the slight curve for fitting in your hand nicer, don't have to bring it around to your left D quite as far with your right hand because of that bend too- intelli-gent piece!
Another, thing i use the advantage/disadvantage of that weight for is zapping small, small dead wood; and throwing out, snapping back around to retrieve hanging rigging line just out of reach! Us lil'guys need all the help we can get in that dept.! My limbs are so short; when i stand up; my legs just barely reach the ground!
One of the reasons i keep a double bowline with 'yosemite ' tie off in my rigging line is to hold 'biner to snap to belt, load or as throwing weight too! In fact another purpose for my steel drop eye pulley on belt is to clip into this line for even more throwing wieght in tree. With that much weight it can easily fly up over branch and come back to ya nicely. Or, work that end to ground pulled by the weight of steel pulley / 'biner and keep other end of rig line for loads. That lil trick really makes carrying that pulley even more powerful strategy.
i generally go up loaded for war; a fella was making fun of me about it; no big thing; i do that myself! But anyway; he said it was too much wieght, but he wears spurs! Kleins at that; at least my barely used anymore spurs are Bashlins with Buckingham wraps. But i think that weight wise spurs are heavier, he says that you carry them diffrent, and thinx belt weight is more fatiguing. Well, in vehichles/ bikes 1# off the wheel weight (unsprung weight) i believe is equal in effect to taking 2# off the vehicle itself i believe. Would that go for foot weight too? Or might he be write; and weight around waist is # for # more fatiguing? It is always one of my arguments about the trade from 'Euc' (tear it all up quick) to tech (care with toys added); when preaching!
O; um, uh; well, uhhhhhhhhh, let's see.............. his lead climber's lanyard is made from dog chain! Y'all ever hear of that? Guy has been climbing 20 years + or so like that!
