The SVR Leveling Rod is a flat, oval shape for the serious user. Sections stack in a pyramid fashion to allow convenient extension of only those sections required for a particular reading. Scales are glare resistant, protected by an abrasion resistant coating and by Crain exclusive molded ribs. Non-conductive fiberglass construction makes these rods safe for use around overhead powerlines. (This is not a live-line tool.) A measuring scale for height and clearance measurement is on the backside of all single scale models. The SVR rods are available in 16 Ft. and 25 Ft. lengths, in two graduations and three metric scales.
