The wedge holding block is mounted onto the the stem bearing tube or strut and held by stainless steel screws.
Clamp Unit Holding Block is used for GRP / Oil filled bearing housings and avoids drilling fastenings.
The holding block, being firmly attached, provides the means for holding the corresponding wedge that makes up the forward part of the stationary cutter.
A line is caught between the stationary cutting blade and the rotating cutting blade. The wedge forces the two blades tightly together, overcoming the resistance of the bearing and instantly cuts the line.
