Here's my specs for 120 Belisle trap boxes used on horizontal or leaning poles.
Dimensions: For 5/8 or 3/4 inch lumber or plywood
Bottom 8” x 18”
Top 8” x 14”
Sides 6 ½” x 14”
Inside Dimensions
Width: 6 3/4 inches
Height: 6 1/2 inches

I use long spring slots on my boxes so that with the trap set close to the bait the animal will be centered to the trap and stable when it fires the trap resulting in consistant humane neck/thorax catches. Whereas if set far in front of the bait the marten may jump a pan trigger, or get thru standard wires, and trigger the trap with its hind quarters resulting in a poor inhumane catch.
