3.5" Bore Hook Lock Retaining Ring Inch

Square steel hook lock retainers are used to hold the rod gland in place within the cylinder tube. They are sold in common lengths and may be cut down with a hacksaw for "in-between" sizes. Square steel stock may be purchased by the foot in bulk to make your own retainers. Lengths over 1 ft. may have to be slightly coiled for shipping but may be restraightened without harm.
