Scaffolding couplers are critical components in construction, ensuring the stability and adaptability of temporary structures by securely connecting scaffolding tubes. These devices enable workers to assemble frameworks safely and efficiently. But how many types of scaffolding couplers exist? Let’s find out. 

1. Right-Angle Coupler  

The most common type, right-angle couplers, join two scaffolding tubes at a 90-degree angle. They are essential for creating standard vertical and horizontal joints, forming the backbone of most scaffolding systems.  

2. Swivel Coupler

Swivel couplers feature a rotating mechanism that allows tubes to be connected at angles other than 90 degrees. These are ideal for diagonal bracing or irregular structures, providing flexibility in complex designs.  

3.Sleeve Coupler

Sleeve couplers, also called linear couplers, connect two scaffolding tubes end-to-end in a straight line. They are used to extend the length of vertical or horizontal members while maintaining structural integrity.  

4.Putlog Coupler

Putlog couplers are designed to attach horizontal putlogs (transoms) to vertical standards. They often have a flat plate on one side to secure boards or planks, making them vital for platforms and walkways.  

5. Beam Coupler

Beam couplers clamp scaffolding tubes to steel beams or other structural elements. These heavy-duty couplers are crucial for anchoring scaffolding to buildings or bridges during construction or maintenance.  

In total, there are five primary types of scaffolding couplers, each serving distinct roles in assembly and load distribution. The choice depends on the scaffolding design, load requirements, and site-specific needs. By using the appropriate scaffolding coupler, construction teams enhance safety, stability, and efficiency on-site.
