Simon James SJJR Holdfasts for 19mm (3/4") holes (Pair)

Adding to cart… The item has been added

These wonderful holdfasts are made by engineer turned cabinetmaker and author Simon James, they have been very cleverly designed with careful attention paid to finding the optimal combination of angles, arm length and temper to work in any solid benchtop, apron or leg from 1" to 3½" thick.

They function superbly, and can almost be set with hand pressure alone, so with a bosh from a mallet they grip incredibly tightly.

To release the holdfasts just bash them on the back and they will pop free.

Simon checks and tests each holdfast, then marries them up in individually matched pairs, so you get very consistent clamping pressures from both.
