How to Choose
- Knock-down (KD) assembly and whether it must be re-openable
- Cam lock + dowel systems vs bolt-and-barrel-nut joints
- Panel thickness and the matching drilling pattern
- Drilling diameter and depth for the cam housing and dowel
- Joint strength and how many times it will be assembled
- Flat-pack / RTA packaging and tool-free or single-tool assembly
Material Options
Zinc die-cast cams with steel bolts give strong, repeatable joints; nylon dowels and housings suit lighter RTA furniture. Metal cams handle repeated assembly better.
Finish Options
Connectors are hidden, so zinc plating for corrosion resistance is the norm; nickel or brown housings can blend with panel edges where visible.

Installation Notes
Bore the cam housing and dowel holes to the system pattern, press in the dowels, insert the cam bolt, drop the cam, and turn a quarter-to-half turn to draw the joint tight. Drilling accuracy is what makes the joint flush.
