Hammer Holding Ball Catch
£5.40 (inc vat)
Used by Cassese underpinners to hold the wedge hammer in position and to enable easy removal and re-fitting. Needs be replaced once a year as the spring loaded ball catch can lose tension causing the wedge hammer to work loose resulting in wedge misfires.
info: DO NOT over-tighten the ball catch when refitting as this will break the thread and always keep at least one spare as when these break your Cassese underpinner will be inoperable.
