Spread of Jaws, 5 inches. The above cut represents a Single Spring Otter Trap. It is used more especially for catching otter on their "slides." For this purpose a thin, raised plate of steel is adjusted to the pan so that when the trap is set the plate will be a trifle higher than the teeth on the jaws. The spring is very powerful, being the same as used on the No. 4 Newhouse Trap. The raised plate can be readily detached if desired, making the trap one of general utility.
Single Spring. Same as No. 2 1/2 but without Teeth or Raised Plate.
No. 31 1/2 NEWHOUSE TRAP.
Single Spring. Same as No. 3 1/2 but without Teeth or Raised Plate.
Spread of Jaws — No. 21 1/2, 5 1/4 inches; No. 31 1/2, 6 1/2 inches. These Traps are the largest smooth jaw, single spring sizes that are made. Professional trappers will find these especially valuable when on a long trapping line, as they are more compact and easier to secrete than the large double spring traps. The springs are made extra heavy.
Note. — The 21 1/2 is practically a single spring No. 3 and the 31 1/2 a single spring No. 4.
