Ruck 4 Inch Tabbed Protection Grille - Galvanized Wire, IP44, 152202

Ruck 4 Inch Protection Grille for Open Duct Ends

This Ruck protection grille covers the open end of a 4-inch round duct or the open collar of a 4-inch fan. It is a galvanized wire guard with tabs that clip it into place. The wire keeps fingers, leaves, insulation scraps and small animals out of the impeller. Air still passes freely through the open pattern. Ruck rates the grille IP44 against debris entering the fan. It weighs 0.2 lb, so it puts no strain on a light duct run. The Ruck data sheet lists it for Classic series fans at this size, and Ruck states it fits all Ruck fans. The part number is 152202.

Fitting and Cleaning a Duct Fan Guard

On a small duct, an open end is easy to forget until something gets pulled into it. Clip the guard onto the open intake when a short duct or a bare fan collar draws air from a closet, cabinet or crawl space. It also suits the discharge end where a small exhaust line ends inside a room. Line the tabs up with the collar, then press the grille in until it seats. Pull it out by hand whenever it needs a clean. A small opening clogs with lint faster, so check it every few weeks. Brush or vacuum the wire, or rinse it and let it dry before refitting. The grille stops solid debris but not dust, so pair it with an intake filter where clean air matters. Keep it fitted while the fan runs so nothing can reach the blades. Check that the tabs still grip firmly after each cleaning. In a cabinet or closet build, a guard on the intake also keeps stored items from blocking the fan. Mark the grille's position so it goes back the same way after each cleaning.
