Relevant Literature and Case Studies


Q: I have a competitor’s filter grille that I am trying to match. How can I find out what the Shoemaker Mfg. equivalent is?

A: Use our handy Cross Reference.

Q: I have a filter grille with a 2" filter depth. Can I only use a 2" filter?

A: No, the 2" depth filter grille will hold a 1" or a 2" filter. There is a tab in the frame to hold the 1" filter in place.

Q: I installed my filter grille and now I can see up into the duct. Is there something else I should have ordered to prevent this?

A: No, the door on the filter grille is reversible. You can remove the filter grille door, turn it around and hang it on the hinges on the new side.

Q: All filter grilles have the hinges on the long side. Does Shoemaker have an option of a filter grille with the hinges on the short side?

A: Shoemaker filter grilles are standard with the hinges on the long side. However, on our surface mount filter grilles, there is an option to change the hinge placement. Please see the FG Hinge Options brochure for more details.
