RV (Caravan) T-Style Door Catch Repair Kit

Those who have plastic T-style door catches on their RV have more than likely broken the arm at least once.  I purchased and replaced my RV's main door catch and proceeded to break the arm on the next trip out. I designed the arms to be thicker than the original to make them stronger and less likely to break. Since installing, I've yet to break one.  I carry extra printed parts in my RV just in case one does break. 

These models provide the necessary parts to repair an RV (Caravan) T-Style Door Catch. The kit is complete for a new install or complete change over of an existing install. Since the arms are thicker than the originals, they may not work with your hinge and catch parts so I've included those parts as well.  These could also be used for more than RV's such as a shed door. I've included various industry-standard arm lengths. If you need a different length then the ones I've provided, leave me a message and I'll try to accommodate and add to the files.

I printed the arms with both PLA and PTEG. PTEG is probably a better choice as it stronger and more flexible and will hold up better to the outdoor environmental elements. I'm sure other filament types will also work.  I recommend printing the arms with a sufficient number of walls to make the arm solid with no infill.  Please report back comments on how these work for you, filament type used, and other useful comments. 

6/3/2026:  I had a Latch Hinge break during my last camping trip due to weak layer-to-layer adhesion. I strengthened the design to decrease possibility of breakage.
