Selection Guides

B/S offers floor expansion join covers to match most floor and floor-to-wall applications. 

BS™ Original Self Aligning Flexible 
Expansion Joint Covers

The key to our system is a centering bar which consists of two wear resistant spheres fastened at opposite
ends of a flat spring steel bar. These act as lubrication free bearings minimising wear on the aluminium and brass tracks in which the mechanism constantly moves.
The bars are positioned diagonally across the joint opening. The spring steel centering bar holds the covers plate central and the fixing screws tight.
