Overview
The Spectra Precision 1239 Extended Height Vertical Pole is engineered for professional pipe laser applications where standard poles fall short. This universal fixed pole provides a rigid, stable vertical support column that positions pipe lasers at precise predetermined elevations above pipe inverts, eliminating interference with pipe centerlines and flowlines during installation. Built from heavy-duty materials with a robust telescoping design, the 1239 extends to accommodate deep manholes, large-diameter precast pipe installations, and challenging gravity flow applications. Its universal mounting compatibility works seamlessly with Spectra Precision pipe lasers and other major brands, while the reinforced locking mechanism ensures zero movement during critical alignment operations. When accuracy and stability matter most—whether you're setting grade on 48-inch storm drain or aligning sewer mains in 12-foot manholes—the 1239 Extended Height Pole delivers the reach and rigidity demanded by today's underground construction professionals.

Job Applications
- Deep Manhole Installations: Extends high enough to position pipe lasers above workers and equipment in manholes exceeding 10 feet deep, maintaining clear line-of-sight while keeping the laser safely out of the work zone
- Large-Diameter Pipe Alignment: Provides the vertical clearance needed for 36" to 72" diameter storm drain and culvert installations where the laser must be positioned well above the pipe invert to avoid interference with pipe sections during placement
- Precast Concrete Pipe Projects: Ideal for gravity sewer and drainage projects using precast sections, allowing the laser beam to remain above the centerline while crews maneuver heavy pipe segments into position without disturbing the laser setup
- Tunnel and Microtunnel Guidance: Offers the height adjustment necessary for tunnel boring applications where lasers must be positioned at specific elevations relative to tunnel inverts, providing continuous grade reference throughout the bore
- Grade Transfer in Utility Trenches: Enables precise elevation control when setting grade stakes or benchmarks in deep utility excavations, giving surveyors and foremen reliable vertical reference points without entering the trench
- Pump Station and Wet Well Construction: Perfect for establishing flowline grades in deep pump stations and wet wells where the laser must remain elevated above concrete pours, rebar placement, and formwork activities

FAQ
- What's the maximum height the Spectra Precision 1239 pole extends to?
- The 1239 extends to a maximum height of 96 inches (8 feet / 244 cm) from base to laser mounting point. This extended reach makes it ideal for deep manholes, large-diameter pipe installations, and applications where you need significant clearance above the pipe invert. The pole also collapses to 48 inches for standard applications and easier transport.
- Is this pole compatible with pipe lasers from other manufacturers besides Spectra Precision?
- Yes, the 1239 features a universal 5/8"-11 threaded mounting head that's industry-standard across all major pipe laser brands including Topcon, Leica, Trimble, CST/Berger, and David White. The tripod adapter base also works with standard laser tripods from any manufacturer. This universal compatibility protects your investment if you use multiple laser brands on different jobs.
- How stable is this pole at full extension compared to shorter poles?
- The 1239 is engineered with heavy-duty 1.5-inch diameter aluminum sections and dual-grip twist-lock mechanisms that prevent deflection even at full 96-inch extension. The reinforced locking collars with safety pin backup ensure zero movement during operation. When properly set up on a stable tripod, the pole maintains laser accuracy within manufacturer specifications regardless of extension height. For maximum stability in windy conditions or high-traffic areas, ensure the tripod legs are fully extended and weighted.
- Can this pole be used for applications other than pipe laser work?
- While designed specifically for pipe laser positioning, the 1239's universal 5/8"-11 mount makes it versatile for other surveying applications including positioning rotary lasers for interior fit-out work, mounting line lasers for vertical reference in tall spaces, or elevating construction lasers above obstacles. The graduated markings also allow it to function as a grade reference pole. However, its primary design optimization is for the rigidity and height requirements of underground utility construction.
