Q: What is the Slimduct MD Indoor Lineset Cover used for?
A:  It’s designed to conceal exposed HVAC linesets, electrical conduit, gas piping, and other types of indoor piping. You can use it in residential and light commercial spaces where a clean, finished appearance is important.

Q: Can you use the Slimduct MD outdoors?
A:  No, it’s made exclusively for indoor use. It doesn’t have UV protection, so it can break down when exposed to direct sunlight. If you need a cover for an outdoor run, the Slimduct SD is the right choice, as it’s UV-stabilized and built for exterior conditions.

Q: What sizes does the Slimduct MD come in?
A:  You have two size options: the MD-751-W (3″ x 2-5/8″) and the MD-851 (3-3/8″ x 2-7/8″). Both accommodate 3/8″ and 1/2″ linesets with 1/2″ insulation, as well as a 5/8″ drain hose.

Q: How many fittings are available for the Slimduct MD?
A:  There are 14 different precision-molded fittings available, so you can handle corners, direction changes, and custom configurations without having to improvise. This makes it a flexible system that works for a wide variety of indoor lineset layouts.

Q: Is the Slimduct MD difficult to install?
A:  The screw-free design and the range of available fittings make the installation process straightforward. For cutting, it’s recommended to use the VD-2200 cutter, and if you’re working in cold conditions, warming the duct slightly before cutting helps prevent cracking.

Q: Why does the Slimduct MD look better than standard lineset covers?
A:  The no-screw design is the biggest visual difference, as no visible fasteners are breaking up the surface. Combined with its clean white PVC finish, the Slimduct MD blends naturally with interior walls.
