This clamp allows you to attach a pool thermometer to the edge of your pool without having to glue on a hook or drill a hole in the edge.

The clamping range with a 30 mm long countersunk screw is approximately 25–35 mm.

The clamping range can be increased by using a longer screw.

Parts:
 

• clamp part 1
• clamp part 2
• 30mm m4 countersunk screw (stainless steel)
• m4 heatinsert 

I would recommend using ASA for better thermal stability.
