Button Ferrule SW-705

The standard button material is carbon steel, but can be ordered as stainless steel if desired. Measure the length using maximum dimensions (from outside end of the ferrule).

You can specify a custom design with a different button length or finish diameter, but please send a sketch of the assembly when you order. Keep in mind that this may reduce the assembly’s rated capacity.
