The round base contains pre-drilled holes, including two holes at 180 degrees and three holes at 120 degrees. The rectangle base contains different combinations of pre-drilled holes which will match up to many electronic devices and mounts, including Marine GPS, CB Radios, Ham Radios, Gimbal Brackets and more. 

Overall Height:
8.125"

Weight Capacity: 
Up to 15 lbs.

RAM® Pin-Lock™ security solutions are designed to withstand the harshest environments where RAM® Mounts are commonly used. With an emphasis on aesthetics and function, RAM® security nuts/knobs are low profile and only add a small amount of additional bulk to your system when compared to the standard knob included. At a fraction of the cost of currently available keyed locking knobs, the additional peace of mind and tamper resistance comes at a very affordable price. 

Material: 
Powder Coated Marine Grade Aluminum and High Strength Composite 

Ball Size: 
2.25" Rubber "D" Ball Size 

Note: 
The 11" x 3" rectangle base is a universal mounting bracket with a selection of mounting hole locations. In certain applications additional holes may need to be drilled for proper fit with your electronic device. 

Recommendations:
For an extra tight grip, RAM recommends the RAM-KNOB9HU Hi-Torq™ wrench. For larger ‘D’ size mounting solutions, RAM® utilizes a larger knob that offers the ideal amount of leverage to properly tighten your mount to prevent slippage in heavy chop or in extreme vibration environments. Use the cold weather wrench to tighten the mount for optimal performance. Aftermarket locking knobs are not capable of tightening the RAM® Mount to the required tension to perform in high vibration applications. The addition of an aftermarket knob will make the mount not compatible with the cold weather wrench and will not be able to tighten properly.
