ABSTRACT:
A tension scale device particularly suitable for measuring pan tension on a leghold trap. The device comprises a housing with a slot and an open front end, a compression member preferably a spring in the housing, and a movable member having a rear portion that telescopes in the housing and a front portion that extends beyond the front end of the housing. The spring is compressed by moving the movable member into the housing. A scale is provided on the movable member together with a slidable indicator. When the front end of the movable member is pressed onto a trap pan or like tension member being measured, the scale indicates the amount of weight or tension being applied to a tension device.
