The fit, finish, glass-smooth bearings are exceptional. The weight rating (36kN, 5kN max working) is well within normal use. However, not being versed in the "Newton" rating, I had to find a conversion to be able to relate to the actual working range. Maybe provide the old English ratings? With the right fittings and shackles, this swivel could be useful in the shop as well as in the dungeon. It has also provided several hours of entertainment as a fidget-spinner during long conference calls. Getchaone!
