The innovative Spring Locking Clip will hold in position a completely loosened refractory anchor to deliver the best result.
The arm of a Rod Lok Anchor is held in place by jamming the interfacing surfaces between the lug slot. The first engagement depresses the metal surfaces slightly; if re-engaged more than once, the lock is weakened. The innovative Pressform Spring Locking Clip will hold in position a completely loosened anchor.
Refractory anchor arms are sometimes knocked over after installation just prior to a refractory cement pour. It may be from an errant work boot, something hitting it by mistake or the physical impact of cement being dropped on the arms from a wheelbarrow above.
