As it addresses the duct ceiling vents usually hook up to the joists over the dry wall ceiling to add balance. When your joists are too much from where you require to spot your ceiling vent, the vent can be attached by you right to the not in the dry wall using dry wall anchors. Without anchors, the drywall is likely to crumble without forming a a good seal round the screw, when you screw into it.
Lay the back of the vent on the ceiling, since the the duct that was open. Mark the holes in every single corner or on each side using a pencil. Make sure that the vent is big enough the marks should be-at least 1/2 inch from the duct. Remove the cover.
Drill a hole to the ceiling dry wall at every mark. The drill bit needs to be smaller in relation to the drywall anchors’ diameter, producing a a safe and a good fit. Drill straight at an angle, maybe not into the dry wall ceiling.
Place the cover on the hole that is duct aligning the holes. Push a dry wall anchor into each hole. The anchors are ribbed, therefore it might take some pressure to get all of them the way in. Faucet them gently with a rubber mallet if required. Do not use a normal hammer, which could split the plastic.
Drive the screws to the anchors using a screwdriver. Most dry wall anchor sets come with screws developed to to suit each anchor. If not, be sure to buy the same dimensions screw to guarantee a a good match and anchor. If feasible, have a buddy assist you support the the vent in location while the screws are added by you. Tighten each screw contrary to the vent. As you tighten the screws, making a protected maintain, then dry wall anchors increase within the dry wall.
