Threaded Lifting Key FAQ
How do I use the M12 Threaded Lifting Key?
Below is a step by step guide on how to use our M12 Threaded Lifting Keys on FAB TRAYTM Access Covers.
Identify where the locking boss is on each cover. Insert a flat headed screwdriver in to the slotted section of each screw. **Note – after some time the screw head can become filled with dirt/debris so this will need to be removed before the slot in the screw head is visible**.
While applying pressure to the top of the screwdriver, turn in an anti-clockwise direction. This will loosen the locking screw. After multiple turns the screw can now be removed and the M12 thread of the boss should now be visible.
With the locking screw now removed and the M12 thread visible you must now take our COM0000310 lifting key and insert this into the top of the boss. Begin by rotating the key clockwise with light pressure applied. The lifting key should now engage into the M12 thread. Continue rotating the lifting key in a clockwise direction until the key feels as if it stops.
Repeat steps 1-3 until all lifting keys are inserted. Now turn each key one by one in a clockwise direction. This will offer some resistance but should lift the cover slightly from the frame work and break the seal between the cover, frame and neoprene seal.
Now the seal between the cover, seal and frame has now been broken the cover can be lifted free from the frame and placed to one side to enable access to the chamber below.
Replacing the cover in the frame is the reverse of removal but ensure that all seating faces are brushed clean and any dirt/debris is fully removed as not to damage the neoprene seal and to ensure correct fitment.
**Note – Over time the cover can become stuck in the frame work with dirt and debris. If this is the case then tap around the top edge of the cover and the frame with a rubber mallet or other suitable tool as this will help dislodge the dirt/debris. Special care should be taken to not damage the cover or frame**
