NO. 3 1/2, OR EXTRA STRONG OTTER TRAP.
This, the No. 3 1/2, has a spread of jaws of 5 inches. This trap is for otter, but is used more especially for catching them 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. If desired, the raised plate can be detached, making the trap one of general utility.
NO. 21 1/2, WITHOUT TEETH.
Single Spring No. 21 1/2 has a spread of jaws of 5 1/4 inches. This trap is the same as No. 2 1/2 but is without teeth or Raised Plate as some trappers prefer it in this style.
No. 31 1/2 Newhouse Trap is also a single spring being same as No. 3 1/2 but without Teeth or Raised Plate. Spread of jaws 6 1/2 inches.
These traps, Nos. 21 1/2 and 31 1/2, are the largest smooth jaw, single spring sizes that are made. Professional trappers will find them especially valuable when on a long trapping line, as they are more compact and easier to secrete than double spring traps. The springs on these traps are made extra heavy.
The No. 21 1/2 is practically a single spring No. 3 and the No. 31 1/2 a single spring No. 4. These traps are used for such animals as otter, beaver, wolf, wolverine, fisher and have been known to catch and hold Mountain Lion.
