SitePro SFBR20-DCB Surveyors Fiberglass Tripod - Heavy Duty - Dual Clamp 42 to 72-inches Extended

The SitePro SFBR20-DCB is a professional-grade fiberglass surveyor's tripod engineered for the rigors of daily construction and surveying use. Built around a dual clamp leg locking system, precision flat machined head, and rugged fiberglass legs, this tripod delivers the rock-solid stability that rotary lasers, total stations, and optical levels demand — even on uneven or challenging terrain. Whether you're setting grade on a commercial slab or shooting elevations across a site, the SFBR20-DCB gives you the reliable platform your instruments deserve.

Overview & Jobsite Applications

Designed for contractors, surveyors, and field engineers who can't afford instrument drift or setup failures, the SitePro SFBR20-DCB combines the thermal stability of fiberglass with heavy-duty aluminum hardware and a flat machined head. Unlike wood tripods that warp and crack or lightweight aluminum models that flex under load, the SFBR20-DCB holds its position on concrete, dirt, gravel, and uneven grade. The 42–72 inch height range covers the majority of instrument setups without awkward crouching or over-extension. The dual clamp system — one at the leg collar, one mid-leg — eliminates the creep and slip common in single-lock designs, keeping your instrument exactly where you set it through the full work shift.

Key Features

• Dual Clamp Leg Locks: Two independent clamps per leg prevent slippage and maintain set height under instrument load and vibration
• Fiberglass Legs: Dimensionally stable in heat, cold, and moisture — won't warp, swell, or conduct temperature changes to your instrument
• Flat Machined Head: Precision-ground flat top ensures instruments sit level and true, with no play between instrument base and tripod head
• Standard 5/8" x 11 Thread: Compatible with the vast majority of professional surveying and laser instruments on the market
• Hardened Steel Leg Points: Drive securely into soil, gravel, or asphalt for maximum ground contact and stability
• Rubber Foot Covers: Protect finished floors and surfaces when working indoors or on concrete
• Wide Stance Geometry: Leg spread engineered for a low center of gravity and maximum platform stability at all height settings

Job Applications

Rotary Laser Layout: Set your rotary laser at precise working height on the SFBR20-DCB's stable flat head and hold grade reference across large floor slabs, site grading, and structural layout without drift or vibration interference.

Total Station Surveying: The 5/8" x 11 thread and rigid fiberglass leg construction support total station setups where plumb and level accuracy must be maintained throughout long observation sessions.

Optical Level Work: Grade checks, elevation transfers, and differential leveling runs benefit from the SFBR20-DCB's height adjustability and dual-clamp stability — set once, shoot all day.

Indoor Construction Layout: Rubber foot covers protect finished concrete and wood floors while the tripod's adjustable height handles suspended ceiling grid, MEP layout, and partition framing reference work.

Frequently Asked Questions

What thread size does the SFBR20-DCB use, and will it fit my instrument?

The SitePro SFBR20-DCB uses the industry-standard 5/8" x 11 TPI thread, which is compatible with the overwhelming majority of professional rotary lasers, total stations, optical levels, and theodolites. If your instrument uses a different thread size, a compatible adapter can be used.

What is the advantage of dual clamp leg locks over a single clamp design?

Dual clamp leg locks secure each leg at two points — the upper collar and a mid-leg position — which dramatically reduces leg creep and slippage under instrument load or when working on sloped terrain. Single clamp designs are more prone to gradual height loss during use, which can throw off level and elevation readings.

Can I use this tripod on finished floors and indoor surfaces?

Yes. The SFBR20-DCB includes rubber foot covers that slip over the hardened steel leg points, protecting finished concrete, wood, and tile surfaces. For indoor layout work, simply cap the leg tips before setup.

How does fiberglass compare to wood or aluminum for surveying tripods?

Fiberglass offers the best combination of dimensional stability, durability, and low maintenance for most jobsite conditions. Unlike wood, it won't warp, crack, or absorb moisture. Unlike lightweight aluminum, it resists flex under instrument load and is far less susceptible to thermal expansion, which can introduce error in sensitive instrument work.
