1/4″ drive reversible ratchet, 72 tooth mechanism

New design.

The reversible 900/55Z has a new 72 teeth mechanism, developed by Beta’s technical department, with 15 teeth always in grip. The workload is spread over a large number of teeth, so as to reduce the wear of each single tooth and guarantee a longer working life. The 72 teeth also guarantee a pick-up angle of only 5° and a very compact head perfectly at ease even in the tightest of spaces. 

Features:
• 15 teeth in contact with gear at all times: increased sturdiness
• 5° take-up angle: increased rapidity
