Some applications make it necessary to prevent interference by unauthorised personnel. This is often the case with complex machinery and systems where changing the delivered condition can result in danger. The PARRYPLUG® offers a quick and clean solution for such cases.
Operating principle
To protect thread connections against tampering, conventional solutions aim to irrevocably destroy the screw drive. On the one hand this requires a high application of force, which can destroy sensitive components and materials, and on the other hand there is considerable added cost for installation and removal. The PARRYPLUG® represents a completely new and innovative solution. The PARRYPLUG® locking principle is guaranteed by specially constructed axial ribs that generate a defined, secure press fit in the screw drive. It thus effectively and permanently prevents tools from interfering with the internal drive. The position in the drive remains unaffected, despite extreme vibration. To take into account the fine tolerances of common hexagon socket drives, these locking elements are manufactured to the highest standard in our own facilities. Use of high‑performance plastic allows for a wide temperature range of ‑50 °C to +200 °C. Customised colours are possible on request.
Smart and easy
Up to six plugs in the magazine enable simple installation without tools. The assembly plate is an installation aid to insert plug into the screw drive. The assembly plate is rotated or tipped to release the plug. The installed PARRYPLUG® thus provides clean and effective protection immediately. Quick and simple – installation is repeated without any further preparation until all of the plugs have been installed.
