105mm (4") - 70mm (3") IVORY SpeediDuct Trunking Reducer Joint RJ-70-105

The Reducer Joint is part of the BBJ SpeediDuct Trunking system which is easy to install and adds the finishing touches to an air conditioning installation by covering up unsightly pipework or wiring to give a clean ivory finish. This quality plastic trunking is fire resistant and weatherproof meaning it can be used internally or externally.
The 70mm Duct range is for pipe sizes up to 3/8" and 5/8" with 13mm insulation and the 105mm Duct range is for pipe sizes up to 3/4" and 7/8" with 13mm insulation.

NOTE: SpeediDuct reducers are used to connect fittings to a smaller size of duct—for example, when branching off from a tee. The larger end of the reducer matches the main trunking size and fits inside the fitting. The smaller end is slightly oversized to allow the smaller trunking to be inserted into it.
