DescriptionWeight (lbs) Right-Angle Wedge Clamp3.30Swivel Wedge Clamp3.74 Wedge couplers are used for making a temporary connection between two tubes: Right angle coupler: connecting two tube in a right angle Swivel coupler: connecting two tubes in any angle The connection is obtained by tightening the flaps of the coupler on the tube and hammering the wedge with a 500 gram hammer. Standard SEM couplers are fully tested and do comply with the European EN 74 standard in the following classes: Class B for right angle couplers Class A for swivel couplers Material The base materials of the couplers follow theChinese standard. All base materials are tested at theauthoritative labaccording toASTM E8-2004 Q345 for U-shaped,wedge,short hold pin and small hold pin. 20CrMo for center rivet of Swivel clamp. Identification SEM couplers are recognizable by a marking in the wedge of the coupler. Quality TheSEM quality department checks the quality of the couplers by means of daily process checks and tests of he couplers. Corrosion protection The couplers are hot dip galvanized and have therefore a lifetime corrosion protection. Use Use couplers only for connecting two steel scaffolding tubes or two aluminum scaffolding tubes with a diameter (1.9 inch)which corresponds with the inside diameter of the coupler. A coupler in which the clamping force on the tubes is provided by tightening the flaps around the tube and by means of hammering home a wedge.Wedge couplers shall be tightened with a 500 grams hammer to the jarring blow. This means two or three blows with a hammer of 500 grams using normal power. We recommend hand and eye protection using wedge couplers. Each coupler should be visually checked before using it. If any coupler is visually damaged or deformed, disqualify the coupler and dont use it anymore.
