The SVR Leveling rods deliver all the same user advantages for which they are well known for, but are now even lighter, more durable, and more compact. They now feature round buttons and collapse to fit behind the seats in most trucks. Tighter locking mechanism that resists jamming from dirt and sand. Constructed of strong, rigid fiberglass with reinforcing ribs for added stability. Water-proof and nonconductive. Special measuring scale on back of each SVR. Rectangular-oval shape allows for wide, glare-resistant scales that are wear resistant.
