Our telescopic pole is made of roll-wrapped manufacture technology , with spiral grain on the tube surface . The advantage is to avoid the tubes instantaneous drop while the clamps are in open condition . The surface of tube is resin color , wear-resistant and scratch resistant .
Compared with extruded poles , tube made of roll-wrapped technology has a lighter weight , better strength and appearance .
Our clamps use spring resistance design , with tube spiral lines , to avoid squeezing the operator's fingers while tubes falling down, and this kind of design also reduce the damage on the clamps caused by severe impact . The strength of the spring resistance can be adjusted by the operator himself .
Our clamps are made by plastic injection molding technology , with high strength PA66 material .
Material of spring is stainless steel to avoid rust . Material of screw is aluminum anodic oxidation .
