CUSH shoe supportIt turns out that my camera roll is a great source of inspiration for iDigHardware posts, especially the “What’s that?” series.  (If you have any photos to share, you can submit them here.)  I tend to notice and appreciate details, and I get a little thrill when I see that someone has taken the time to install hardware with the correct components.

I’ve shared several posts about various parts and pieces – coordinator brackets, ratchet release assemblies, etc., and today’s posts addresses an LCN Closer component called a CUSH shoe support.  It’s that small angle on the face of the frame, up above the door closer shoe.

When installing a parallel arm closer from LCN, it’s important to use five screws to attach the parallel arm shoe to the underside of the frame head.  This is especially critical when the closer has a CUSH or Spring-CUSH arm.  These arms have a built-in stop to stop the door in the fully-open position, so the connection between the shoe and the frame has to handle the extra force generated by the stop.

When the jamb depth of the frame is not wide enough to install the fifth screw (typically when the reveal is less than 3 1/16-inch), the CUSH shoe support provides a way to install the screw, helping to ensure a strong connection.  The CUSH and S-CUSH arms have two different holes that can be used for the fifth screw, to provide two options depending on the configuration of the frame.  Refer to the installation instructions here.

What other parts and pieces have you seen “in the wild”?  Let’s build a library of “What’s that?” photos and explanations!
