Use Cases

Finish and protect AC installations

Use ducts, couplers, elbows, and end fittings to enclose and route exposed line sets. Use weatherstrip to seal window AC gaps, covers for winter coverage, and sleeves for standard thru-the-wall units.

How to Choose

Start with fit and route

For line set coverage, compare 77 mm and 100 mm system compatibility, straight duct length, and whether the route needs a coupler, end fitting, 45-degree elbow, or 90-degree flat elbow. Check color to coordinate with the exterior.

Planning Guide

Plan the right fit before choosing

Line Set Coverage

Plan the exposed line set route before selecting fittings

Straight duct sections provide coverage for single or multiple exposed line sets, while fittings complete direction changes, connections, and run terminations. White options coordinate with neutral or painted facades; a brown 90-degree flat elbow provides another finish option.

  • Choose 77 mm components for matching 77 mm duct or cover installations.
  • Choose 100 mm components for matching 100 mm (3-3/4 in.) line set cover systems.
  • Use 45-degree vertical or flat elbows for angled route changes.
  • Use 90-degree flat elbows for right-angle transitions, a coupler to join duct sections, and an end fitting to finish a run.
Window and Wall Units

Match accessories to the unit installation style

Window AC accessories address gaps around the sash and seasonal outdoor coverage. A thru-the-wall sleeve is intended for a standard 24-inch air conditioner installed through an exterior wall.

  • Open-cell foam weatherstrip helps seal gaps between the sash and air conditioner while cushioning vibration.
  • The small outdoor cover fits window air conditioners up to 10,000 BTU and is intended for winter weather coverage.
  • The white galvanized steel sleeve measures 25-1/2 in. L x 17-1/2 in. W x 15-1/4 in. H and includes adjustable mounting hardware.
  • Front and rear sleeve cover panels seal the sleeve when the air conditioner is removed.
Portable AC Equipment

The 25 ft cam lock cable set is specifically for compatible KPO12-43 portable air conditioning units. Its listed details include 6/4 SO wire and cam lock connections for the specified 12-ton, 460V indoor/outdoor portable AC models.

  • Confirm the portable AC model before choosing the cable set.
  • Use the 25 ft length when an extended cable run is needed.
  • Verify that the specified 6/4 SO wire and cam lock connections match the equipment.
