Pegs Locking Hooks™ are pegboard hooks that don't fall out of the pegboard.  Once inserted, they lock into place and will not come out until you want them to.

Pegs Locking Hooks™ fit most standard pegboards from 3/16" to 1/4" thick with holes 1/4" to 9/32" diameter.  For more details, visit pegslockinghooks.com.
