Speedway Expansion Coupler
Speedway Expansion Couplers (EXP) are recommended for those installations where the maximum and minimum temperatures are such that the expansion and contraction of the cable ladder installation is a consideration.
Expansion Couplers are designed to allow for a maximum movement of 28mm. Speedway expansion couplers are supplied singly and complete with all necessary ladder fixings (8 fixings supplied with each coupler).
The Expansion Coupler should not be installed without a support either side of the expansion joint within 600mm. Specific recommendations covering the spacing of expansion couplers and the setting gap at the time of installation are given in the Datasheet download.
