Читать книгу Steel Traps - A. R. Harding - Страница 38

This, the No. 3½, 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.
