Not every spring-loaded part on an RV cabinet does the same job. Some hinges pull the door closed, free-swing hinges let it move without closing pressure, and overhead door supports hold an upward-opening door open. This guide compares exact JR Products and RV Designer part numbers so you can choose the correct mechanism before ordering.
Three different cabinet-door functions
Self-closing cabinet hinge
A spring applies closing pressure. Use this style when the door should be encouraged to stay shut, alongside suitable cabinet catches if needed.
Free-swing flush hinge
The hinge lets a cabinet door pivot without the same self-closing spring action. Choose based on the original mounting footprint and desired feel.
Overhead hold-open support
A separate spring hinge or telescoping support helps an upward-opening door remain raised while you access storage.

Cabinet hinge and support model comparison
Manufacturer part numbers matter: JR 70585/70595 are self-closing, while 70605/70615 are free-swing. RV Designer H271, H277 and H279 are all 6¼-inch spring-loaded door supports, but their construction differs.

What to check before replacing cabinet hardware
For H271, H277 and H279, RV Designer's installation instructions require securing the eyelet to the frame as a pivot, positioning the upper flange for the desired door angle, and confirming screws will not penetrate the cabinet door. Heavier doors may need two supports. Follow the exact manufacturer's installation instructions.

A new hinge may not solve a cabinet door that swings open during travel if the catch or strike has failed. Compare JR barrel, roller, magnetic and push-release cabinet catches. For a mechanism that holds an exterior door open, see the RV entry and compartment door-holder guide.
