SitePro 01-ALQR40-B Aluminum Quick-Release Dome Tripod
When your crew is moving between setups all day, every second of instrument transition time adds up. The SitePro 01-ALQR40-B aluminum dome tripod is engineered for contractors who demand fast, repeatable instrument mounting without compromising the rock-solid stability that precise grade control requires. Its quick-release dome clamp system lets you swap instruments in seconds, while heavy-gauge aluminum construction keeps the platform rigid on uneven terrain, compacted fill, and rough concrete decks alike.
Overview and Jobsite Applications
The ALQR40-B is purpose-built for commercial construction, civil grading, utility layout, and structural plumb work. Whether you are running a rotating laser level across a slab pour, setting up a total station for column layout, or using a theodolite for angle verification, this tripod provides the consistent, vibration-damped base your instrument needs to perform within spec. The dome head design accommodates a wide range of 5/8-inch by 11-thread instruments and offers smooth pan adjustment for quick re-orientation between shots.
Key Specifications
- Material: Heavy-gauge aluminum alloy legs and casting
- Head Type: Dome (ball) head with quick-release clamp
- Thread: 5/8 inch x 11 — compatible with most professional surveying and laser instruments
- Leg Design: Double-banded for torsional rigidity
- Leg Tips: Replaceable steel points for ground penetration; compatible with rubber feet for hard surfaces
- Extended Height: Approximately 64 inches (varies with leg extension)
- Collapsed Height: Approximately 40 inches — compact for transport and storage
- Weight Capacity: Rated for professional-grade optical and laser instruments
- Color: Black anodized finish for corrosion resistance

Key Features
- Quick-release dome clamp for fast, tool-free instrument mounting and swapping between setups
- Double-banded leg bracing resists lateral flex when legs are spread on uneven ground
- Heavy-gauge aluminum construction delivers a high strength-to-weight ratio for all-day carry without the fatigue of steel
- Adjustable leg friction clamps hold extension position firmly on slopes and soft soil
- Replaceable steel leg tips bite into dirt and sod for a secure plant; swap to rubber caps for concrete and finished floors
- Black anodized finish protects against oxidation in wet and humid conditions
- 5/8 inch x 11 dome head is universally compatible with rotating lasers, pipe lasers, theodolites, and total stations
- Compact collapsed length stows in a truck bed, gang box, or instrument vehicle without interference
Job Applications
Concrete Slab and Foundation Layout: Plant the ALQR40-B on compacted subgrade or existing slab and use the quick-release dome to mount a rotating laser. Swap to an optical level for elevation checks without breaking down the tripod between tasks.
Structural Steel and Column Plumb: The double-banded leg design minimizes vibration transfer from nearby equipment, keeping your theodolite or total station stable during angle measurements on active steel erection sites.
Utility and Underground Layout: Lightweight aluminum means one person can carry the tripod and instrument bag from manhole to manhole without a second crew member. Steel leg tips penetrate soft shoulders and disturbed backfill for a solid setup.
Finish Grade and Site Grading Control: Set up once, use all day. The friction leg clamps maintain height across repeated moves on sloped terrain, and the dome head allows quick re-leveling without full disassembly between grade rod shots.

Frequently Asked Questions
- What instruments are compatible with the SitePro 01-ALQR40-B?
- The ALQR40-B uses a standard 5/8 inch x 11 thread dome head, which is compatible with the vast majority of professional rotating laser levels, pipe lasers, optical levels, theodolites, and total stations. If your instrument uses a tribrach, a 5/8 x 11 tribrach adapter will allow full compatibility.
- Is the dome head interchangeable if I need a flat-top or threaded head?
- The dome head on the ALQR40-B is designed as the primary mounting interface, but SitePro offers compatible replacement head assemblies and adapters. Contact our team at Express Tools to confirm the correct adapter for your specific instrument.
- How does the quick-release clamp differ from a standard wing-nut dome tripod?
- The quick-release clamp uses a lever or cam mechanism rather than a threaded wing nut, allowing you to mount and secure an instrument in a single motion. This significantly reduces setup time when moving between multiple instrument stations throughout a workday.
- Can this tripod be used on concrete or finished floors without damaging the surface?
- Yes. The ALQR40-B ships with steel leg points designed for soil and soft surfaces. Replacing them with rubber foot caps — available separately — protects polished concrete, epoxy floors, and tile from scratching while still providing adequate grip for indoor instrument work.
