SECO 4852-16 Heavy-Duty Column Clamp

Overview

The SECO 4852-16 Heavy-Duty Column Clamp provides a stable instrument mounting platform for industrial surveying, construction layout, structural monitoring, alignment, and other applications where a conventional tripod may be impractical.

Designed for instruments with a standard 5/8-11 mounting thread, the clamp secures to both round and square columns using a heavy-duty ratchet and a 2-inch-wide, 10-foot strap. Its adjustable mounting column rotates and moves vertically, allowing the instrument to be positioned and oriented for the required line of sight.

The assembly is constructed from structural aluminum with stainless-steel hardware for demanding industrial and field environments.

Heavy-Duty Column Mounting

The SECO 4852-16 provides an alternative to a tripod when a suitable structural column is available.

The clamp can be attached to compatible round or square columns, making it useful in industrial facilities, manufacturing environments, structural interiors, bridge work, and construction locations with limited floor space.

Mounting the instrument directly to a structural column can help keep the work area clear while providing a stable equipment position.

Standard 5/8-11 Instrument Mount

The adjustable column features a standard 5/8-11 mounting stud for broad compatibility with surveying, scanning, alignment, and construction instruments that use the same threaded connection.

Compatible equipment may include:

• Construction lasers
• Surveying instruments
• Laser scanners
• Monitoring equipment
• Alignment instruments
• Compatible tribrachs and adapters

Instrument weight, mounting requirements, and thread compatibility should be verified before use.

Rotating Adjustable Column

The instrument-mounting column can rotate to orient the equipment toward the required work area.

This rotational adjustment helps position the instrument without needing to loosen and reposition the entire clamp assembly around the structural column.

Once the desired orientation is reached, the mounting system should be securely tightened before operating the instrument.

12-Inch Vertical Adjustment

The adjustable column provides 12 inches, or 30.48 cm, of vertical movement.

This height adjustment allows the instrument position to be raised or lowered to achieve the required line of sight, clear nearby obstructions, or align the equipment with a specific measurement plane.

15-Inch Instrument Stand-Off

The distance from the centerline of the 5/8-11 mounting stud to the supporting column is 15 inches, or 38.1 cm.

This stand-off distance positions the instrument away from the column, providing additional clearance for equipment rotation, operation, and line-of-sight measurements.

Heavy-Duty Ratchet and Strap

The clamp includes a heavy-duty ratchet and a reinforced strap measuring:

• 2 inches wide
• 10 feet long
• 5.08 cm wide
• 3.05 m long

The strap is rated for a 2,200 lb load and creates a strong connection around compatible round or square columns.

The stated rating applies to the strap itself and should not be interpreted as the mounted-instrument capacity of the complete column clamp assembly.

Round and Square Column Compatibility

The ratchet-strap mounting design allows the SECO 4852-16 to attach to both round and square structural columns.

Possible mounting locations include:

• Steel columns
• Concrete columns
• Structural posts
• Industrial supports
• Bridge members
• Large pipes or cylindrical structures
• Compatible beams and framework

The mounting surface should be structurally sound, clean, and suitable for supporting the equipment and clamp assembly.

Structural Aluminum Construction

The main clamp assembly is manufactured from structural aluminum.

This construction provides the strength required for industrial applications while helping keep the assembly more manageable for installation, adjustment, and transportation.

Stainless-Steel Hardware

Stainless-steel hardware provides durability and corrosion resistance in areas exposed to repeated adjustment and field conditions.

The hardware should be inspected regularly and tightened according to the mounting requirements of the instrument and work environment.

Ideal Applications

• Industrial surveying
• Construction layout
• Structural monitoring
• Building interior measurements
• Plant and factory surveying
• Bridge and infrastructure work
• Laser scanner mounting
• Construction laser setup
• Machinery and equipment alignment
• Confined-area instrument setups
• Locations where tripod use is impractical
