The 133-00034 is a two-piece cable tie assembly with a fir tree mount designed for secure fastening into round holes. It is engineered for panel thicknesses from 0.06" to 0.16" and hole diameters of 0.31" to 0.33". This 8.0" tie accommodates bundle diameters up to 1.77" and provides a minimum tensile strength of 50 lbs. Constructed from heat-stabilized Polyamide 6.6 (PA66HS), it operates in a temperature range of -40°F to +221°F. The fir tree mount provides low insertion force and high extraction force, and the integrated disc helps prevent rattling in high-vibration applications.
