Hugo Brennenstuhl 1679680 Светодиодный светильник заливного света,

Rectangular Cable Transits

Made from 6mm mild steel, frames have a standard internal width of 120mm. All have a removable end, which permits retrospective fitting to existing cable or pipe entry through walls or floors. They may be used in either vertical or horizontal fitting applications. A complete assembly will require a number of filler "blocks" chosen from the "U" section types, the "flexible" blocks, and the solid blocks. Also required will be n+1 stayplates, where n equals the number of rows of filler blocks, and a presswedge that finally completes the seal.
