SitePro 01-ALQR40-B Heavy-Duty DOME Head Aluminum Tripod with Quick Clamps

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
• Carry Bag: Included canvas or nylon leg bag

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.
