CR-5 COIL ROD – SUPER 150 HI-STRENGTH
Meadow Burke supplies two different types of coil thread:
1) 20 KIP and 40 KIP series uses standard hi-strength, 3-1/2 pitch coil thread (CR-4).
2) 60 KIP series uses Special Super 150 hi-strength, 4 pitch coil thread (CR-5).
They are not interchangeable and cannot be mismatched.
Use only Meadow Burke coil rod for all hold down application. Meadow Burke will not guarantee the SWL of any coil rod which has been field welded, bent and/or has worn threads. Coil Rod Threads must protrude through top of swivel to achieve SWL. Use two CN-5 Coil Nuts or one CN-25/CN-33 Coil Nut to develop Coil Rod SWL.
