Twist Tight Ties
The unique shape of Twist Tight Ties insures tighter fabric tension. Ideal for high security uses.
The ties will be a preformed steel wire ties. It shall be preformed in the shape designed to fit around the post or rail, and over at least two sides of a diamond of the chain link fabric. The two ends shall come together and are long enough to be power twisted with a tool. The twist shall be at least three full twists equivalent to one and one half machine turns, drawing the chain link fabric tightly to the post or rail thereby increasing the effectiveness of perimeter security detection devices through reduction of false alarms due to environmental causes.
The twisted ends shall lay opposite of the fabric side away from human contact to reduce the possibility of untwisting the tie.
If contact is unavoidable on the twisted side, the protruding “tail” shall be bent down to the pipe to prevent injury. Or the tie design for side application may be used as an alternative in lower security applications that allow contact with the “tail” (or termination point of the tie).
No less than a nine gauge wire should be used with a 1.8 ounce galvanized coating or 1.2 ounce if the chain link mesh is 1.2 ounce, or .04 ounce aluminized.
Tie should meet ASTM F 626-96a (2003) 18.104.22.168. Power Fastened Round Wire Ties.
