We offer this vintage fixed right-angle tubing clamp, also known as a scaffolding clamp, or a pole clamp, depending on use. It is used to connect two pieces of pipes at a right angle with thumb screws. It measures 2 1/2″ long (not counting screw length) x 1 1/2″. Both screws move in and out. It shows surface rust due to age. Please see photos for more detail.
