Door catch

Use: This door catch was designed to secure a folding shelf in a travel trailer during transit. Can be used for other applications like keeping a cabinet door closed or main door open.

Design Update: 6/2/2023-Due to how popular this model has been and some good feedback on a need for smaller sizes I made two new smaller designs than the original. The original is now the large and I have added a medium and small version.

Large-With PETG material the force to separate the catch is around 12 lbs. Two female versions to account for straight or side mounting. Holes sized for #8 screws.

Medium-With PETG material the force to separate the catch is around 6 lbs. Two female versions to account for straight or side mounting. Holes sized for #6 screws.

Small-With PETG material the force to separate the catch is around 2 lbs. Two female versions to account for straight or side mounting. Holes sized for #4 screws.
