12" Linear High Velocity Plaster-In Outlet

Add a modern touch to your space with our 12" Trimless Plaster-In High Velocity Outlet. The minimalist linear design (1/2" wide) runs a full 12 inches — moving significantly more air than a single short outlet while keeping the same barely-there profile that disappears into your ceiling or wall. Available in straight or 90-degree configurations, with eight connection types and two rough-in lip depths to suit any system and finish. For dimensions and product drawings, use Free project help.

Even Airflow, Edge to Edge
Distributing air evenly across a 12-inch slot is where most linear outlets fall down — the ends starve while the middle roars. Ours doesn't. Fed by three connection points along its length and shaped internally with guide vanes and airfoils, the body splits and steers the incoming air so it arrives smooth and even across the entire 12" span. No hot center, no dead ends — uniform comfort along the full length of the outlet.

The Art of Invisible Comfort
Our premium high-velocity outlet covers represent the perfect fusion of engineering excellence and architectural aesthetics. Designed to integrate with most high-velocity HVAC systems, these outlets disappear into your space, delivering powerful performance without compromising your design vision.

Engineered Versatility
Choose straight or 90-degree geometry, then pick from eight connection types to match your tubing: 2", 2.5", and 3" ends in tapered, clamp-style, and non-tapered (ESP) options, plus a Twist Fit end compatible with 2" Unico Twist-Fit and SpacePak Twistlock. Whatever high-velocity system you're running — Unico, SpacePak, or Hi-Velocity by ESP — there's a direct connection for it, with the 90-degree version engineered to fit within standard 2x4 wall construction.

Invisible Integration
Unlike traditional vents that interrupt clean lines and modern aesthetics, our high-velocity outlets virtually disappear into your ceiling or wall. The perforated rim features an ultra-thin profile specifically engineered to be plastered over, creating a flush transition with the mounting surface. The result is a barely perceptible outlet that maintains the architectural integrity of your space.

Installation
The rough-in design features a separate frame and body with pre-drilled mounting holes for direct stud/joist attachment, allowing precise frame placement before wallboard goes up and final body installation after the wall is finished. Choose the lip depth to match your finish: 1/16" for joint compound or 1/8" for plaster.
