Easydeck Modular Staging - End Cap to Fit Staging Frames - 30mm x 30mm. Each end cap can be used to fill in 'the hole' where the wooden unit slots of top of the module frame. This creates an even and smooth surface with no sudden holes. Easydeck is a 'no fuss' system, which is simplicity itself to install and requires no special tools to assemble. Can be used with either the 750mm or the 1 metre units.
