Gully Trap Fevice For Shower(Smaller Drainage)

[Guest Yun Hyuk Han]

Hi everyone I'm looking for 2 x Gully Trap Device for my 5 room bto bathrooms. These gully trap devices are for preventing insects and mosquitoes from coming up through the drainage holes. They are particularly the smaller ones for the shower drain and they are roughly about 11cm/4.5" in diameter size. Currently HDB have provided me with the drainage cover but not the gully trap devices. I'm hoping anyone of you guys out there could assist. Help is very much appreciated.
