Right Angle Coupler is a special clamping tool which is used to join two pipes perpendicular to each other in a scaffold staircase to build a strong and reliable structure which is capable to withstand heavy loads of the crew members working at the construction site. It helps to reach the various parts of an under construction building and for the transportation of the required materials to different heights. Right Angle Coupler is manufactured with premium quality metals like pressed and carbon steel which provides greater strength to the structure and prevents the swaying and vibration of the skeletal structure of the stairs.
