The Lock Climber Doubles Up as a Set of House Keys and a Coupling Link

The Lock Climber is a handy dual-function device for rock climbers looking to reduce the amount of items they have on them during a climb by fusing together a coupling link and a house key into one design. The device cleverly works to keep rock climbers safely secured to their ropes while also doubling up as a key to unlock a residential space.

When rock climbers are out ascending walls and mountains, the gear they have on them is extremely limited as they need to be agile and have a full range of motion. That's where the Lock Climber comes in, doubling up as a carabiner and key in one design. The gadget looks like a standard key but has a loop top part that is fitted with an adjustable lock for ropes.
