A Flat Protection Grille Sized for 16 Inch Duct
At 16 in the opening is large enough that anything can walk into it. This grille caps it with galvanized steel sheet in a low-profile pressing, rated IP44 for dust and splash. Airflow through the free area stays close to unobstructed. It adds 0.2 lbs to the assembly.
Where This Duct Guard Belongs in the Run
On a duct this size the grille is doing structural work as well as exclusion, spanning an opening wide enough for a rodent. Fit it at the exposed termination. It does not filter, and adding fine mesh at this diameter would cost real static pressure. Keeping the face clear matters as much as fitting it, because a grille packed with leaf litter is a restriction and at this diameter you notice the loss quickly. The pressing matches Ruck collar sizes, so it seats without an adaptor. Treat it as a mechanical guard rather than part of the sealed path, because it makes no attempt to be airtight.
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.
- 16 in Duct Fit: Matches Ruck 16 in collars and standard 16 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.
