Swivel Mount Adapter: 1" Wide Base + 1" Extension
Add-On Baseplate for Adjustable Swivel Mounts
This is an **ADD-ON** baseplate designed to work with our standard Adjustable Swivel Mounts (using the ~1.8" wide base attachment).
Purpose: Allows installation on narrow trim (minimum 1 inch wide) AND adds exactly 1 inch of forward extension.
Swivel Mount is NOT included - Purchase this only if you already have or are purchasing a compatible Swivel Mount separately.
Solution for 1-Inch Trim & Adding 1-3/8" Total Depth!
Is your door trim exactly 1 inch wide, or slightly wider, but too narrow for our standard swivel mount base? Need to push your swivel mount forward by over an inch? This adapter baseplate is designed for this scenario!
It features a 1-inch wide wall footprint for secure mounting on these specific surfaces. It also provides a fixed 1-inch forward extension, plus a 3/8" transition section, adding a **total depth of 1-3/8 inches** to your installation. The plate then flares out to perfectly connect to our standard swivel mount bases.
