The anchor loads generated by using this type of Axial Expansion Compensator are high. A guide bracket with low frictional resistance should be used.

Please note these units are not suitable for use on a drop rod system and need to be suitably guided (e.g. DST 253 Slide Guide or DST 114 Roller Chair and Guide). Please consult the Expansion Compensator Application Guide for positioning of anchor points and subsequent support centres. (See Page 114)
