• 60% the weight of metal poles:  2.1 lbs.
• Non-conductive. Not affected by humidity, temperature extremes or corrosion. Impact resistance materials.
• One Year Warranty.
• Standard prism offset of 0.427 ft.
• Adjustable 5/8 x 11 adapter may be pre-set within a 0.27 ft. range to accommodate a broad range of prism heights.
• Revolutionary non-slip Grip-Tite locking mechanism: eliminates elevation errors from lock slipping. High-strength elastomeric pads grip the telescopic sections. The lock is self-centering and can be adjusted with an allen wrench.
• Topo-boot stores conveniently under the level: Another innovative, exclusive feature. The Topo Boot screws over the precision point and increases the area of the point for use on soft surfaces in topo shots. The Topo Boot is removable and stores under the level vial when not in use.
• Precision Point: A replaceable precision tip/point is standard on the Composilite Prism Pole. In the even that the precision point wears or is damaged it can be replaced in the field. The tip is constructed of a special hardened stainless steel.
• Level: A large level vial is standard on the Composolite Prism Pole. This large vial makes plumbing a breeze. The level vial is adjustable with an allen wrench.
• H.I.: An adjustable prism mount with lock nut is standard. Additionally specific offset adapters are available for a variety of prisms.
• Includes level, topo-boot and tip

Forget about inaccurate readings due to a slipping pole--the new Quik-Lok will get the job done quick with its fast setup and positive clamping.

All Quik-Lok poles feature sturdy and dent-resistant aluminum construction. The pole's top section is anodized and imprinted with permanent graduations warranted for life; the bottom section is electrostatically powder painted for durability. The pole is designed to be easily cleaned and serviced. Adjust clamping tension yourself to suit your needs. The Quik-Lok's wide clamping surface will not scratch pole graduations, and assures a tight clamp. Each pole includes a circular level vial and a replaceable hardened steel point.

• 10ths and metric (every 2mm) graduations
• Precise adjustable 5/8" X 11 mounting stud to suit all commonly used prisms
