Types of Scaffold Tube Clamps Explained for US Scaffold Buyers
Scaffold tube clamps are the essential connectors that hold tube-and-clamp scaffolding systems together. Because these clamps directly affect the stability, load-bearing capacity, and safety of your structure, scaffold buyers across the United States must understand the different types available in the market. Selecting the right clamp not only improves efficiency but also ensures OSHA-aligned safety on job sites.
Right-Angle (Double) Couplers
Right-angle couplers are the most commonly used scaffold tube clamps. They create 90° joints between standards and ledgers, forming the primary load-supporting framework. Because these clamps carry vertical and horizontal loads, choosing high-quality, galvanized versions is essential for long-term durability.
Swivel Couplers
Swivel clamps are ideal for bracing and for complex scaffolding designs that require angular adjustments. They allow tubes to be connected at almost any angle, making them perfect for industrial plants, curved structures, or irregular layouts. However, they are not intended for primary load-bearing positions.
Sleeve Couplers
When scaffold buyers need to extend tube lengths, sleeve couplers become important. These clamps join two tubes end-to-end, maintaining proper alignment and strength across longer spans. Their stability ensures that extended structures remain safe during high-load operations.
Putlog (Single) Couplers
Putlog clamps are lighter fittings used to fix transoms or putlogs to ledgers. Although they don’t carry heavy loads, they play a crucial role in floor and platform support.
Because each clamp type serves a different purpose, scaffold buyers should evaluate their project requirements before ordering. For detailed selection guidance, read our full guide on scaffold tube clamps.
