“does anybody else use lockers to rack your cams so you don’t drop them while climbing?? when you rack up for the pitch, just remember to check all of them are fully locked. when black totems are like $115 a pop, i want to make sure they stay safely on my harness.
for anybody else that does this, do you prefer screw locks or double/triple action lockers?? thanks”
History of the lap link in rock climbing.
Chouinard’s invention of the Rugby shirt birthed an explosion of off width climbing. Those developing such, soon ran into problems racking gear. In the tight confines of the cracks and chimneys, the long Perlon on the Nuts would dangle down below the Swami belt and tangle with the spring on the Stitch Plate, coming loose. This presented a safety concern not only for the leader, but also for the helmet-less followers of St Yvon’s aesthetic philosophy. Socks worn inside beenies and chalk bags under bandana’s were no match for a number 10 Hex descending from on high.
Lap links came on the scene. One could smash them closed with a wall or alpine hammer, fixing the gear to the gear sling. They were pried apart with a bit from the bolt kit or a knifeblade piton.
Bill Forest came out with Tetons. Slung with webbing instead of thick static cord, they didn’t require such wide openings to un-rack.
Yvon introduced the Super Long Dong, then the Crag Hammer for extra prying leverage.
Greg Lowe swaged a little keeper cable on the link for use as a belay plate. (citation needed)
Then the lap links limitations started to be apparent. Some of the first instances of anxiety over micro fractures in climbing gear had the campfire discussions and mental health counseling sessions hopping. REI dropped them from their catalog after rumors they were culturally appropriated from Northern Scandinavians. The last nail in the seam for the lap link came when Ace Hardware released a warning regarding galvanic corrosion when racking Copperheads and Pecks.
Climbing in some long forgotton Rocky Mtn cirque or on some friable desert basalt column, you may still come across one of these bits of history.
Attached to an old lead sleeve lag bolt or hanging from faded SuperTape or quarter inch Goldline, left as a rappel ring by some long gone climber backing off something too scary to finish. If so, pause for a moment ——-and replace that sucker with some new gear rated for climbing.
