The HD M.A.S.S. Connector converts one of our dog bone cutouts in a platform, cargo shelf, or drawer top into a threaded connection point for mounting an accessory. Its 3/16-inch steel nut plate spreads the mounting force over a wider area.
What Is a Dog Bone Cutout?
Look for two round openings joined by a narrower slot. This is the dog bone cutout. The HD M.A.S.S. Connector fits into that opening to create a threaded connection point.
Round centers are 1 inch apart. The illustration uses the nominal L-Track opening diameter of 0.785 inch and slot width of 0.420 inch.
The top pad sits above the surface and the steel nut plate sits below. Tightening the two assembly bolts pulls the nut plate against the underside. Your accessory bolts into the center threaded point.
Cutout illustration uses nominal L-Track reference geometry. Connector view is from our installation instructions. If your mounting location already has a threaded connection point, you do not need this connector there.
Do You Need This Connector?
Dog Bone Cutout: Connector Needed
Use an HD M.A.S.S. Connector when you need to turn an unthreaded dog bone cutout into a threaded mounting point. Check the locations where your accessory will attach.
Already Threaded: No Connector Needed
If your product already has a threaded connection point where you are mounting the accessory, you do not need this component at that connection point.
Check each mounting location individually. You only need connectors at the dog bone cutouts you are converting. Follow your accessory’s installation instructions to identify the mounting locations and required hardware before choosing a pack size.
How It Installs
Position your accessory first to identify the cutouts you will use. The connector’s lower plate inserts through the cutout, then pulls against the underside as you tighten the two assembly bolts. The accessory mounts on top and bolts into the connector.
The installation requires a 2.5 mm Allen wrench. Tighten only enough to draw the lower plate against the mounting surface; do not flex the top plastic pad. Where clearance below the connector is limited, the instructions explain how to replace the longer assembly bolts with the supplied shorter bolts.

Great upgrade from the standard connectors that came with my fridge slide. Installation and removal of the fridge slide is a breeze now!

These are a great upgrade to the previous version.
But where’s the “check box” for the adapters?
