The unobtrusive profile of CastSlot sits neatly within concrete, asphalt, and block surface finishes. CastSlot features an electro painted ductile iron throat section, which is securely fixed to the galvanised steel channel body to provide an exceptionally robust yet discreet drainage system. Available with a 30mm opening and a Treadsafe option, which reduces the slot opening from 30mm wide to 2 x 10mm wide slots. The NEW through spacer gives designers the flexibility to pass cables or other services through the channel throat as well as detail additional reinforcing for CastSlot and UltraSlot products. The new locking design ensures alignment and a tight fit prior to taping and pouring.
