The NSS-R is a ratchet-style spanner used to tighten or loosen bolts and nuts when installing or dismantling makeshift scaffolding brackets in shipyards.
- Since a bolt head or a nut does not go through the spanner opening due to the stop block in the upper part of the NSS-A and the NSS-R,
a worker does not lose his balance and can work safely even if he works on a high place.
- As a ratchet-style spanner, the NSS-R is an efficient product that does not need repeatedly inserting and taking out when tightening or
loosening a bolt. With the NSS-R, the job can be finished at once.
How to use
Use these spanners with the scaffolding bolt of the head size 32(bolt spec. M22) only.
Do not exceed the rated capacity specified on the spanner.
