Steel Triangle Baseboard Return Grilles

Steel Triangle Baseboard Return Grilles

Steel triangle baseboard return grilles cover an angled low-wall return opening near the floor, pulling room air back into the HVAC system through a triangular fin profile. Within the Steel Return Grilles range, AirGrilles stocks the triangle baseboard style in 2 colors, brown and white, with widths of 12, 14, 24, and 30 inches at a single 6 inch height. The stamped steel face carries 1/3 inch louvers set at a 30-degree angle, with no sharp edges and no damper, since a return opening pulls air in rather than controlling the volume pushed out. For the straight, non-angled version of the same low-wall return, AirGrilles also carries a Steel Baseboard Return Grille in the same family. Bulk pricing runs across 6 quantity tiers with savings up to 30%, orders of 500+ units qualify for custom production, and in-stock items ship the same day on orders placed by 11AM ET.

A Return Grille for Angled Low-Wall Openings

Steel triangle baseboard return grilles cover a low-wall return opening with an angled fin profile instead of a straight rectangular face, pulling room air back to the system. Within the Steel Return Grilles range, the triangle baseboard style fits the same low-wall placement as a straight baseboard grille, but for an opening that calls for the angled cut. The stamped steel face carries 1/3 inch louvers set at a 30-degree angle, with no sharp edges on the finished stamping. No damper sits behind the face, since a return opening only needs to let air pass back to the system.

Fixed Louvers and a Single Height

Steel triangle baseboard return grilles use fixed louvers set at a 30-degree angle across the face, with no damper and no moving parts behind it. Every width in the range shares the same 6 inch height, so the duct opening's height stays fixed and only the width changes between the 12, 14, 24, and 30 inch models. That fixed height keeps the ordering decision down to one measurement, the opening's width. The 1/3 inch louver spacing matches the same detail used on the straight steel baseboard styles in the range.

Sizing, Color, Bulk and Custom Orders

Triangle baseboard return grilles are ordered by the duct opening, measured width by height, never by the outer cover, the same way as other steel return grilles. For a straight, non-angled low-wall return opening, Steel Baseboard Return Grilles cover that style instead. Bulk pricing spans 6 quantity tiers: 1, 2-10, 11-20, 21-49, 50+, and 100+, with savings up to 30% at the higher tiers. Orders of 500+ units qualify for custom production depending on size, finish, and lead time, and in-stock items ship the same day on orders placed by 11AM ET.

Common Questions About Steel Triangle Baseboard Return Grilles

These answers cover the louver, damper, sizing, and ordering questions that come up most on steel triangle baseboard return grilles.

Does a triangle baseboard return grille include a damper?

No, triangle baseboard return grilles have no damper, since a return opening pulls air back to the system rather than needing volume control. The fixed louvers sit at a 30-degree angle across the face. For the damper-equipped supply version at the same angled opening, a triangle corner baseboard supply register is the supply-side counterpart.

What is the difference between this and the Triangle Corner Baseboard Supply Register?

Triangle Corner Baseboard Supply Register delivers conditioned air into the room through a multi-shutter damper, while the triangle baseboard return grille pulls air back to the system with no damper at all. Both share the same angled fin profile and low-wall height. Check the product title and the presence of a damper to confirm supply or return before ordering.

How do I size a triangle baseboard return grille?

Measure the duct opening width and height, then order by that listed size rather than the visible cover on an old grille. Widths run 12, 14, 24, or 30 inches, and every model is 6 inches high. Check the outer dimensions on each product listing before ordering a replacement.

What if the return opening is straight instead of angled?

Steel Baseboard Return Grilles cover a straight, non-angled low-wall return at the same floor-level height. A triangle baseboard return grille only fits an angled cut, not a flat rectangular opening. Measure the actual opening shape before choosing between the two.

What colors do triangle baseboard return grilles come in?

The range ships in brown and white, both finished with a powder coat baked onto the steel. Match the color to the surrounding baseboard and trim. Check the product listing for the latest color availability by size.

Is there a bulk discount on triangle baseboard return grilles?

Yes, bulk pricing applies automatically across 6 quantity tiers, with savings up to 30% at the 50+ tier. Orders of 500+ units qualify for custom production depending on size, finish, and lead time. In-stock items ship the same day on orders placed by 11AM ET.
