Window Channel Block & Tackle

Question

Hello.  I need to replace a Caldwell 17-4 DQ window channel block & tackle.  It measures 18 inches length, 1/2 inch width, and 9/16 inch depth.  I have attached photos. Please tell me which part I can order that best matches the Caldwell 17-4 DQ.

Hi there!

With this combination of attachments, you could have either an S380-18 or S385-18 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need a spring strength option of 1740.

If you have any further questions just let us know!
