David White AL8-26 Professional Automatic Level Package
The David White 45-8926-1C package delivers field-proven optical leveling performance trusted by contractors and surveyors across grading, construction layout, and elevation work. Built around the AL8-26 automatic level with 26X magnification, this complete kit arrives ready for immediate deployment on any jobsite. Whether you are setting finish floor elevations, shooting grades across a large site, or establishing benchmarks for a foundation pour, the AL8-26 gives you the sharp, reliable sightings professionals depend on. The included 13-foot inches-graduated measuring rod and heavy-duty aluminum tripod complete the system so there is no need to source components separately.
Overview & Jobsite Applications
The AL8-26 automatic level uses a magnetic dampening compensator to self-level within its working range, eliminating the need to manually set a precise level plane before every shot. Once the instrument is roughly leveled via the three-screw leveling base and the bubble vial is centered, the compensator takes over and holds the line of sight true. This self-leveling feature dramatically reduces setup time on active construction sites where the instrument may be moved multiple times throughout the day. The 26X magnification objective lens provides clear target definition at typical construction distances, making it straightforward to read rod graduations accurately even in challenging light conditions.

Job Applications
Site Grading & Earthwork: Shoot grades across cut-and-fill areas with confidence. The 26X optics and long rod reach allow rod readings at distances typical of grading operations, reducing the number of instrument setups needed across a large pad.
Foundation & Footing Layout: Establish and verify elevation benchmarks before and after forming footings. The AL8-26's accuracy rating supports the tight elevation tolerances required for slab-on-grade and stem wall construction.
Building Construction & Finish Elevations: Transfer elevations from benchmark to floor, wall, and ceiling control points. The compact instrument head fits comfortably on a standard tripod inside partially framed structures where space is limited.
Drainage & Utility Work: Calculate invert elevations and pipe slopes for storm, sanitary, and utility installations. The stadia function lets crews quickly estimate horizontal distances when needed without additional equipment.

Frequently Asked Questions
- What does the 45-8926-1C model number refer to?
- The 45-8926-1C is the full package model number assigned by David White to identify the complete kit — AL8-26 instrument, 13-foot inches rod, and aluminum tripod sold together. The AL8-26 is the instrument-only designation. When ordering this listing you receive the complete three-piece package.
- Can this level read metric rods as well as the included inches rod?
- The AL8-26 instrument itself is optics-only and can read any rod placed in front of it. The included rod is graduated in inches. If your project requires metric or feet-and-tenths readings, a separately purchased rod in those graduations will work with this instrument without any modification.
- What is the maximum useful range for accurate rod readings?
- David White rates the AL8-26 for accuracy at 1.5 mm per km of double-run leveling. For practical construction use, rod readings at distances up to 200–250 feet are common. Beyond that, mirage, heat shimmer, and the limits of the 26X optics can reduce reading confidence. For long sight lines, multiple shorter setups are recommended.
- Is this instrument compatible with a standard contractor tripod?
- Yes. The AL8-26 uses the industry-standard 5/8" x 11 TPI threaded base, which is compatible with virtually all contractor and surveying tripods sold in North America. The included aluminum tripod uses this same thread, and any replacement or spare tripod with 5/8" x 11 threads will mount securely.
