A Q-Lok made in 1999 was for sale in a
Thrift shop in Calgary, Feb. 2022. It was
identified by the unique inscriptions on
the cap face. 23 Years old and still works!

The unit was in good working order. It
was taken apart and still in perfect
working order as shown here.
It has seen a lot of abuse and usage but
otherwise intact.

This is a testament to the incredible
durability and design of the Q-Lok, a
design that has only improved in
materials since without any modifications
to the original mold or parts
