This is a modular wall hook rack.

You can choose between four rack rail sizes, the rack rail is available with and without screw holes for mounting with tape:

• 4xHooks 260mm
• 3xHooks 180mm
• 2xHooks 100mm
• 1xHook 20mm

And 4 different hook styles, each in normal (20mm) or slim (10mm) width.

Keep in mind, that the slim versions won't completely cover the mounting holes at the ends of the rack.

There is also a coupler to combine rails.

Use M3x10 screws to secure the hooks to the rack.
