When bringing a duct into a chamber, Bell-Mouth sometimes called ‘chamber entry connectors’ offer a further level of quality finish. Bell mouths provide a smooth duct end whilst stopping the duct from pushing into the chamber and restricting access on the inside.
Used to keep length of pipe separate whilst laid, ducting spacers clip onto lower pipe whilst the above layer sits in the pre-cut mount. This allows multiple layers of pipes running parallel without the risk of damage from movement.
Ducting spacers are made to customer specifications meaning any and all diameters can be accommodated for during fabrication.
Standard sizes include 2, 4, 6 and 8 way spacers.
Couplers are used simply to join to existing pieces of pipe together, usually the same manufacturer but some i.e. 100mm sewer pipe couplers will fit most 100mm sewer pipe regardless.
