Thank you for viewing. This is a Snap-on 3/8" locking ratchet. The screw in the middle of the locking component in the second photo is missing, so it has been replaced with another one, but there are no problems in use. Model: FHX80A Size: 300mm Simple operation has been confirmed. It has been used, so there are scratches and scuffs, but there are no problems with the gears, etc. No claims and no returns, please.
