The RAM® Slide-N-Lock™ Universal Dock Plate (RAP-315U) makes it fast and easy to secure your VESA plate–mounted monitor to the RAM® mounting system.Ideal for shared workstations, fleet vehicles, kiosks, or other high-traffic environments, the built-in key lock mechanism adds an essential layer of protection against theft or unauthorized removal. When access is needed, the keyed design makes it easy to release and remove the monitor for maintenance, device swaps, or relocation—providing both security and convenience in one solution. The top plate features both the 75mm and 100mm VESA hole patterns, providing broad compatibility with most monitors and displays. On the bottom, an AMPS hole pattern offers seamless integration with a wide range of RAM® mounting components, allowing for flexible setup options across vehicles, workstations, and industrial environments. Build a complete, durable mounting solution by pairing the dock plate with a RAM® round ball base, double socket arm, and mounting base of your choice. For smaller monitors, we recommend the RAM-202 (C Size, 1.5" Ball), while larger displays are best supported with the RAM-D-254U (D Size, 2.25" Ball) for added strength and stability.
