seized krab gates

I have been donated some alloy karabiners by someone who has retired from caving. The sleeves on some of them
have stuck shut. I have tried WD40 & pliers but no luck so far. Any suggestions on how I may free them ?

Loading/flexing is likely the best way to open them.

Once you've released the locks you can lubricate the threads with chapstick.

Loading closer to the gate, rather than along the back, will stretch it more, for the same force applied.

A hanger on a bolt in the wall is good for this (suspending the karabiner upside down from the narrow bit of the pear), and a maillon on a footloop to apply the force (you have to hold it in place to stop it slipping down while stepping in the footloop).

Jammed krabs aren't necessary a reason to discard, I find it amazing how tightly an inexperienced caver can do up their Stop attachment karabiner when they notice it's loose while their weight is on the rope!
White splodges of Aluminium hydroxide, grooves / pits from corrosion and wear in the 'hooked' load bearing section are far more sensible reasons to retire.

The screwgate threads aren't particularly finely engineered and shouldn't need greasing, I've always found that washing the mud out is more useful than lubrication.

Repeated gentleish tapping (eg with another krab) can work wonders to unstick screw gates. The number of times I've had to do it with novice climbers/cavers despite the reminder not to do it too tight!

Speaking of which...... I once got confused and used a Prit-stick instead of chapstick - couldn't really complain though.


(Due respect to M Jones for the above)
