The Cable Bullet cable rail system was designed for use with 5/32", 7x7 cable. 

Cable Bullet crimp sleeves are sized to fit 5/32" cable. The use of 7x7 cable is highly recommended. 7x7 Cable is bound in 7 bundles of 7 strands each for superior strength and improved flexibility. The added flexibility allows for clean angles, especially on sloped sections. 316 Marine grade stainless steel cable is highly corrosion resistant and suitable for use in even the most demanding ocean-front environments. Using 316 marine grade stainless steel for both interior and exterior applications ensures long lasting durability and beauty.

The manufacturer's minimum rated breaking strength is 2,400 lbs. Working load limit is approximately 700 lbs. Please Note: Although the cable itself will support these loads, the Cable Bullet cable rail system will not. 

Sold in 50', 100', 250' or 500' spools.
