Ok, here goes.
I don't know what brand the tray was but it is a super el-cheapo and really junk. I should have bought Rubbermaid. I paid $2.50 at Dollar General for it.
I cut most of 3 sides off the tray. I cut 8 5" lenghts of 300# mono. Notice the 4 holes in the back of the tray. I cut between each pair of holes for the strap. The holes are basically for stress relief. If I had cut 2 slots without them, the box would have cracked.

I flared one end of the mono pieces by pushing them against a hot piece of iron, (Heated with propane torch)

I pointed the other end by clipping the end diagonally with small, sharp dykes.

Strap installed. Back of basket.

Completed stripping basket.

Take the same concept and make a lap stripping tray out of a tote lid. Sorry for the poor quality photo. White lid and clear mono not good for photography.
