Inaba Denko Slimduct Coupler
A genuine Inaba Denko Slimduct coupler (SJ series) for joining two lengths of Slimduct straight duct end to end.

Available in 75mm (black or white) and 100mm (black).

Installation & compliance
For use with Inaba Denko Slimduct SD trunking. Butt the two duct lengths together inside the coupler and fix the duct to the wall as normal. Refrigerant pipework inside the trunking must be installed and tested by a suitably qualified F-Gas certified engineer; the trunking itself does not need F-Gas certification to buy.
