What on earth is a DPR you may ask – and the answer is: “Device for Preventing Rotation” and a very useful “widget” to help panel builders locate locks securely in non-metal doors – a regular problem for users/specifiers of non-standard cabinets.
This is a common problem, particularly with insulated or GRP doors and panels. The device allows simple punching/cutting of a round hole with the ability then to fit the anti-rotational adapter which provides secure location for a standard EMKA lock with its rounded corner square body.
The “DPR” has a simple 2-pin location and can be used either as a first-fit or as a post-fit operation, especially on difficult materials or for moulding into GRP doors. It is suitable for all locks requiring a standard EMKA-type rounded 20mm square hole, and so for all their ¼ turn lock housings and related handles such as traditional T, L and wing handles – it is especially useful for our extended housing range, to accommodate extra thick doors – where an adapter may be used front and rear for extra positive location if required.
