Block and tackle balance

A handy person from hillsborough, NJ says:
I have a 1/2" block and tackle balance stamped 273000H does this mean anything to you? Is it simply for 2720 window. The top looks similar to 19-005 and the 15-004 or -005. What series do you recommend?

Thanks,

Mario

I'm afraid I cannot tell what Series you have based on this information. You will have to compare the dimensions of your shoe to those that we show for the 15-004 and 15-005. That is the only way to know which of those is a match.

OK took better measurements: the metal portion of the bar is 28" long. The shoe is black in color and measures 1 1/16" in overall length and 1 1/8" high or width when looking at profile view. If looking at it from a plan view perspective it has "tabs" on it that are about 15/16" across. the top is about 1 1/4" lomg and 1/2" wide and woff white in color, do these dimensions match any of your block and tackle balances? Thanks.

We don't really have anything that matches those dimensions. I'm a little lost, too, to be honest. I'm not sure what you're calling length or width. Have you seen the dimensions we show for the 15-004 and 15-005? I think you should compare your measurements to what we show, and then tell me where they differ. That might be a more clear process.

yes I did check against those dimensions they match up with 15-004 and the 19-002 top pretty much. If I ordered a coiple to try are they returnable if they are wrong?

Sure, check out our Return Policy for more information.

If you have a 19-002 top and 15-004 bottom, then our Series 350 may be a good match for you.
