Suction Cup Base, Plastic, Locking
3.25 diameter suction cup base has a rotating locking mechanism that pulls a strong suction for secure adhesion to the mounting surface.  Compatible with any diamond-shaped mounting plate (RAM-A-238U, RAP-B-238U,RAM-B-238U, RAP-105-6DDU, etc.).  Also can be mounted directly to the back of some device cradles - such as the RAM-HOL-TAB12U.  This mounting base has a smaller diameter than the RAM-B-224U rubber suction cup, is more secure, but it is taller. 

Note: I prefer the RAM-B-224U rubber suction cup mount to this suction cup mount because it is easier to mount, can't damage your canopy, and is less tall. But this RAP-224-1U is more secure than the RAM-B-224U.

Note: The RAP-224-1U suction cup pulls a very strong suction so you may not want to use it on an expensive glider canopy.  If you decide to use it, I am not responsible for any damage to your canopy.  That said, I have used it on glider canopies safely using a trick.  Before you apply it to the canopy, turn the locking ring halfway through its rotation.  Then press it against the mounting surface and turn it the remaining distance to lock it in place.  If it doesn't mount securely enough, try only turning the locking ring 1/4 turn before you apply it to the mounting surface, etc.

Note: If you use suction cups to mount items to a club owned or syndicate owned glider canopy, please be considerate and clean the canopy when you are done flying.  If we don't do this simple step it is likely that the club will ban the use of suction cup mounts - which would be a shame.
