Tope puerta con retenedor

thingiverse

Secure the door with a retainer, preventing wall damage and keeping the door in place to block drafts. Two 4mm screws are required for the two retainers. The first one should be a 4x50 screw depending on the floor type, going through the shim and the lag bolt of 25, depending on the floor type whether it's a concrete slab or a wooden floor. The second one goes in the front lag bolt to add more stability, using a 4x20 screw no longer than that. There must be at least 2mm of clearance below the door.
