Lock for Wooden Shelf Support – securely holds your shelf in the correct position and prevents it from falling or shifting.
 

The model is designed for support pins with a 5 mm diameter.
 

Installation is simple and can be handled by any experienced DIY enthusiast:

1. Print the support locks and the included template.
2. Use the template to mark the screw hole position on the shelf.
3. Pre-drill the hole using a small, thin drill bit.
4. Attach the support lock to the shelf (use a 3×16 mm or 3.5×16 mm screw – the screw length depends on the thickness of your shelf).
