Baseboard Supply Registers for Low-Wall Airflow

Baseboard supply registers deliver conditioned air from a low-wall opening near the floor, where the register sits below eye level along a wall's base. Within the Supply Registers range, the baseboard style is built for that specific opening, distinct from return baseboard grilles that pull air back to the system instead of delivering it. A back or wood flap damper controls the volume on most baseboard supply models, which return grilles typically do not include. That damper is the quickest way to tell a baseboard supply register apart from a baseboard return grille on sight.

Choosing Straight, Triangle, Corner or Wood Baseboard Registers

A straight baseboard register fits a standard low-wall opening along a flat run of wall, without any corner or triangular cut. A triangle baseboard register fits an opening where the duct exits at an angled cut rather than a straight rectangular one, and a corner baseboard register fits an opening that sits at or near a wall corner. A wooden baseboard register fits the same low-wall openings in a material that blends with hardwood trim and flooring instead of painted steel. Duct opening size decides the fit within each style, not the outer face size.

Sizes, Materials, Bulk and Custom Orders

Baseboard supply registers are ordered by the duct opening, measured width by height, never by the outer cover. On the straight steel style, the outer face runs about 1-1/4 inches larger than the opening, so a 12"W x 6"H opening uses a 13-1/4"W x 7-1/4"H face that overlaps the hole, and the exact delta varies by style, so confirm the outer dimensions column on each product listing. For the plain steel style measured here, Steel Baseboard Supply Registers covers the straight, non-corner openings in the range. Bulk pricing spans 6 quantity tiers: 1, 2-10, 11-20, 21-49, 50+, and 100+, with the 12"W x 6"H steel register falling from $18.09 at a single unit to $14.48 at the 50+ tier, close to 20% off. Orders of 500+ units qualify for custom production depending on product type, size, finish, and lead time, and in-stock items ship the same day on orders placed by 11AM ET.

Common Questions About Baseboard Supply Registers

These answers cover the style, material, sizing, and ordering questions that come up most on baseboard supply registers.

What is a baseboard supply register?

A baseboard supply register is a low-wall register that delivers conditioned air into a room from an opening near the floor. The range spans 4 styles, straight, corner, triangle, and wooden, across 2 materials, steel and wood. Most models carry a damper behind the face for volume control.

Is a baseboard register the same as a baseboard grille?

No, a baseboard supply register includes a damper for airflow control and delivers air into the room, while a baseboard return grille pulls air back to the system and typically has no damper. Both sit at the same low-wall height along a wall's base. Check the product type before ordering to confirm supply or return use.

What is the difference between a straight and a corner baseboard register?

A straight baseboard register fits a standard opening along a flat run of wall, while Steel Corner Baseboard Supply Registers fit an opening that sits at or near a wall corner. Both are ordered by the duct opening, not the outer face. Confirm the opening's location against both styles before ordering.

What materials do baseboard supply registers come in?

The range covers 2 materials, steel and wood, in 4 colors, black, brown, oak, and white. Steel styles wear a powder finish, and the wooden style ships in natural oak. Match the material to the room's trim and flooring before ordering.

When should I choose a triangle baseboard register instead of a straight one?

Choose a Triangle Corner Baseboard Supply Register when the duct exits at an angled cut rather than a straight rectangular opening. A straight baseboard register only fits a flat, rectangular low-wall opening. Measure the actual opening shape before choosing between the two.

Does AirGrilles offer decorative fin patterns on baseboard registers?

Select styles in the range carry 3 decorative fin patterns: Art Deco, Basket Weave, and Pinstripe, alongside the standard louvered face. Availability depends on the specific style and size ordered. Check the Model filter on each collection page to confirm which pattern ships in a given size.

What if the baseboard register needs to match hardwood trim instead of painted steel?

Wooden Corner Baseboard Supply Registers cover the low-wall openings in natural solid oak, finished to take stain and match existing trim. The steel styles in the range ship in black and white instead. Both are ordered by the same duct opening measurement.

Is there a bulk discount on baseboard supply registers?

Yes, bulk pricing applies automatically across 6 quantity tiers. On the steel style, a 12"W x 6"H register drops from $18.09 per unit to $14.48 at the 50+ tier, close to 20% off. Orders of 500+ units qualify for custom production, and in-stock items ship the same day on orders placed by 11AM ET.
