The B&G W-75 Carrying Strap should work with all 1 and 2 gallon B&G sprayers.
We would recommend attaching the B&G W-75 Carrying Strap to the "D" ring attached to the plastic protective top. Here's why:
1. If you attach to the handle, the strap will interfere with pumping action
2. The "D" ring is off the center of the tank making it a little more natural to carry
3. The "D" ring can be replaced if it breaks, by installing a new plastic tank top.
Older B&G's have the "D" ring welded to the tank. If you break that, you have to find a good stainless welder to repair.
