This is Pro-Line's Better Edge System Sanding Block for R/C Bodies.
First, Pro-Line introduced the Better Edge Sanding Drum for the perfect wheel well. Now, they’ve added a new product to finish off the perfect straight edge, as well as all the nooks and crannies of your RC race body. PROTOform's new Better Edge Sanding Block is yet another tool for the racer who takes pride in finishing off their concourse-worthy race body.
Pro-Line’s Better Edge Sanding Block is formed from injection molded nylon with a shape that is both racy and ergonomic. Use the straight edge to smooth out scissor imperfections along the bottom edges or rear wing of your body, then you can rotate the block to finish off tightly curved edges such as the rear of your 1/12 or 1/8 scale on-road bodies, off-road body wheel wells or suspension cutouts. The rounded ends of the block are two different radius sizes for different applications, 1/4 in and 1/2 in. It can also be used to sand parts and tires.
Each block includes a form-fitted strip of high-grade, 120-grit'sand paper that’s fastened to the block with a low-profile hook-and-loop system. A spare strip is also included for your convenience and replacement strips (PRO610801) are also available in 2-packs.
