Jameson's Single Corner Block is a 60 degree model featuring one row of nylon rollers. Corner blocks evenly distribute pressure on coax or fiber cable when pulling around corners. Steel side plates with straight base act as a strut for increased strength. Nylon axle bushings provide easy swivel and longer axle life. Adjustable keeper arm holds cable in place as it is pulled through block. Corner blocks are used to make cable placement easier.
