Integrated wedge concept: friction-free, smooth, parallel wedge movement eliminates flange damage and spreading arm failure.
Unique interlocking wedge design: no first step bending and risk of slipping out of joint.
Requires very small access gap of only .24 in. (6mm)
Stepped spreader arm design: each step can spread under full load.
Few moving parts means durability and low maintenance.
Safety block SB1 and ratchet spanner SW22 included.
