Muncy™ SB Buttons

Muncy Uses Premium Steel for its SB Buttons

Muncy specifies material for its buttons stops that is conducive to better swageability and strength. As such, Muncy’s wire rope buttons are time tested, having been made for over 50 years. With better swageability comes better die life: less wear on swaging dies.

Muncy Steel Button Ferrule Applications

Carbon Steel Buttons seem to have an eclectic array of product uses, from picking up pipe (with a Muncy Tea Cup) to on a roll-off truck (with a Muncy Roll-off Hook). Some buttons are swaged on cable every few inches for conveyor applications and others used on the end of the rope to be placed inside a drum.

SB Buttons are recommended for use on 6x19 or 6x37 IPS or XIP, EIP, XXIP, EEIP, RRL IWRC wire rope. Before using SB Buttons with any other type lay, construction, or grade of wire rope, it is recommended that the termination be tested to prove the adequacy of the assembly in the intended application. Proper swaging practices are the assembly manufacturer’s responsibility.
