With the aid of serrated locking plates GN 187.4 standard components can be interlocked and firmly set at a defined angle.
The angular position of the fixing bores in relation to the serrations is not defined in the standard design. The exact positioning is available as special design.
The range of designs makes these plates adapt-able for almost any application in this particular field. To complement these serrated locking plates, accessories such as guide pots GN 187.1 and thrust springsGN 187.2 are useful additional standard parts.
