Description
This expansion bolt stretcher has fittings at each corner and at the ends of the crossbars.
When the mechanism in the fittings is operated, the corner will open in a fully controlled and reversible manner.
It can be compared to a traditional key stretcher, but the fittings allow the stretcher to be opened as necessary, while also avoiding the stress generated by mechanical shocks on the key.
Standard thicknesses: 22 mm and 35 mm.
