Ruck 10 inch Flat Protection Grille | Galvanized Steel, IP44

A Flat Protection Grille Sized for 10 Inch Duct A flat grille sits almost level with the duct collar, which is the point of it. There is no basket standing proud to catch a sleeve or a hose. Galvanized steel sheet does the work, rated IP44 against dust and splashing water. At 0.2 lbs it adds nothing to the run. Where This Duct Guard Belongs in the Run Fit it at whichever end is exposed. On an exhaust termination it stops birds and insects entering against the dead fan; on an intake it keeps leaf debris out of the impeller. Note that this is a coarse guard, not a filter. It will not stop dust, and it is not meant to. For that you want an intake filter box upstream. Check it each season, because a grille that has silted up costs you static pressure. Ruck sizes these to their own collars, so the fit is a push rather than a fight. There is no gasket and none is needed, because the grille is not a pressure boundary. Key Features Galvanized Steel Sheet: Resists corrosion in humid exhaust air and outdoor terminations. IP44 Rated: Rated against dust ingress and splashing water at the duct mouth. Low-Profile Flat Pressing: Sits close to the collar, so nothing projects into a walkway. 10 in Duct Fit: Matches Ruck 10 in collars and standard 10 in ducting. 0.2 lbs: Light enough that it changes nothing about how the duct is supported. Pest and Debris Exclusion: Stops insects, birds and leaf litter entering an idle duct.
