ABSTRACT:
A pest guard comprises a flat disk mounted on a cylindrical sleeve which is fixed against linear movement on a support member by a pair of clamps. The sleeve is provided with a longitudinal slot permitting it to be placed over the support member. The clamps are each formed by two halves and adapted to be fitted over a respective ends of the sleeve so that the clamps permit rotational movement of the sleeve but inhibit longitudinal movement of the sleeve about the cable. The disk is provided with a central opening such that it is permitted to rotate about the sleeve. The disk is also provided with a radial, curved slit which resists opening and which maintains the disk flat through extended use.
