'Speed Groover' R10 rolled radius plate for Robo Joiner

The Speed Groover large radius plate attaches effortlessly to your Robo Joiner unit, and when used in conjunction with the RJA-1 Swivel Kit for extension poles (purchased separately) it allows you to cut grooves earlier in the process by gliding over the concrete surface. No need to step on. It also works well on firm green concrete. 

R10 radius groove, 25mm deep, 350x310 mm plate.
