D-451 is my inventory # only. Here is a used, good-working heavy duty , older USA made Stanley steel banding/strapping TENSIONER high-tension tool. It is for CLOSED style seals. It will work with 5/8" thru 1-1/4" widths. There is a # 1 on the handle where it says Stanley, not sure if that is the older model?To release the ratchet once it is clamping or pullubg, push the handle all the way forward so you can slide the tool forward and release it. The little yellow ball on the handle was glued back on at one time, this is not a threaded ball.
It should work with group # 5, 7, 8 and 9 closed seals and low or high carbon, 302 stainless steel metal strapping.
