Q235 High Quality Construction Scaffolding Accessories Scaffolding Couplers

Right angle coupler:A coupler used for connecting two tubes crossing at right angle.
Class A and class B right angle couplers have the same requirements,except that class B couplers have a higher load capacity.And a minimum requirement for torsional rigidity.
Swivel coupler:A coupler used for connecting two tubes crossing at any angle.
Parallel coupler:A coupler used for connecting two parallel tubes.
Sleeve coupler:A coupler used for jointing two tubes located co-axially and whose purpose is to transmit tensile and compressive and bending forces.
Class A and Class B sleeve couplers have the same requirements except that class B couplers have a minimum requirement for strength in bending and a higher tensile strength requirement.There are two basic types of sleeve couplers:Sleeve coupler functioning by friction and sleeve couplers working with shear pins.
Putlog coupler:A coupler used for fixing a putlog or transom to a ledger.
Loose spigot:An internal component used for aligning tubes co-axially and able to transmit compressive forces.
