Corner Blocks are used to guide coaxial cable around corners. The MIG welded steel frames are designed on a strong 17" radius and support the rollers on 2" center. Durable aluminum rollers are compatible with synthetic winch lines. Proper alignment of the cable to the input end of the corner block will ensure minimum friction, ease of pull-out and quality installed cable. The cable keepers can be set to the true degree of the corner. Quad cable blocks are supplied with three rows of 1" synthetic and one row of 1-1/4" aluminum rollers. Dual row corner blocks are also available as Model K-468J-2P and M370J-2P.
