SitePro 01-ALQR20-B Heavy-Duty Head Aluminum Tripod with Quick Clamps

The SitePro ALQR20 Aluminum Quick-Release Tripod (01-ALQR20-B) is the no-nonsense support solution professional contractors reach for when setup speed, instrument security, and all-weather durability are non-negotiable. Whether you're running grade checks, setting benchmarks, or shooting elevations across a muddy slab, this tripod keeps your optics locked and level through an entire shift.

Overview: A Tripod That Works as Hard as Your Crew

Built from heavy-gauge aluminum, the ALQR20 shrugs off the rust, dents, and grime that sideline cheaper stands. The quick-release clamp head accepts any 5/8-11 threaded instrument — rotating lasers, optical levels, theodolites, total stations, and receivers — so you swap gear in seconds without hunting for a hex key. Leg extensions lock with positive-grip clamps that don't loosen over a full day's vibration from nearby equipment. This is a tripod engineered for crews who throw gear in truck beds, work in rain, and can't afford downtime chasing wobbly setups.

Key Features

• Quick-Release Clamp Head: Snap your instrument on and off in seconds — keeps pace with fast-moving crews swapping setups throughout the day
• Heavy-Gauge Aluminum Construction: Resists corrosion, handles rough transport, and provides rigid, vibration-damping support for precision optics
• Wide Height Range (24"–60"): Works at grade-check heights and full standing height without a second tripod on the truck
• Positive-Grip Leg Clamps: Lever locks stay tight even on uneven terrain and high-vibration environments near heavy equipment
• Universal 5/8-11 Thread: Compatible with virtually every professional laser, level, and optical instrument on the market
• Stable Footprint: Wide-stance leg spread digs into soft ground and resists wind tip-over on open sites

Job Applications

Concrete & Flatwork: Lock in a rotating laser at the right height before the pour and leave it running — the ALQR20 holds position through foot traffic and screed vibration without drifting.

Framing & Layout: Set a plumb bob laser or optical level at mid-wall height and carry reference lines across an entire floor plate without re-leveling every time you move the instrument.

Grading & Excavation: The 24"–60" range covers everything from grade rod work in shallow cuts to elevated sightlines over berms, and aluminum legs push cleanly into soft dirt without sinking.

MEP Rough-In: Electricians, plumbers, and HVAC installers use the quick-release head to hot-swap a pipe laser and a point-transfer laser at a single station, cutting setup time between trades.

Frequently Asked Questions

Will the ALQR20 fit my rotating laser or optical level?

Yes. The ALQR20 uses the industry-standard 5/8-11 thread, which is compatible with virtually all professional rotating lasers, optical levels, theodolites, and total stations. If your instrument uses a different thread or a tribrach mount, a 5/8-11 adapter resolves the fit in most cases.

How does the quick-release clamp work — is it secure enough for precision work?

The quick-release clamp uses a lever-actuated jaw that firmly grips the instrument's mounting stud without requiring tools. Once locked, the clamp holds the instrument against lateral movement and vibration. It is designed for professional-grade instruments and is appropriate for optical levels, rotating lasers, and theodolites used in construction layout and grading.

Can I use this tripod on uneven or soft ground?

Absolutely. The aluminum legs have pointed feet that penetrate soft soil and gravel, and the independent leg adjustment lets you compensate for uneven terrain. The positive-grip lever clamps keep each leg locked at its set length even when the tripod is shifted or bumped during work.

What is the difference between this tripod and a fiberglass model?

Aluminum tripods like the ALQR20 are lighter, more resistant to physical impact, and easier to transport in truck beds without cracking. Fiberglass tripods offer better thermal stability — they expand and contract less with temperature swings — making them the preferred choice for high-precision survey work where sub-millimeter accuracy over long sessions is critical. For most construction layout, grading, and MEP work, aluminum provides more than sufficient stability at a lower weight penalty.
