Easy to install without special tools, it ensures a professional finish and safeguards your work from day one. ## Description The Lineset Box is the first and only line set rough-in box on the market. It provides a professional, weathertight termination point on the exterior wall for refrigerant copper lines, condensation drain, and low voltage control wiring. Designed for HVAC contractors working in new construction, the Lineset Box protects your line set from the moment you rough in until you return to set the condensers, no more showing up to find your copper kinked, bent, or ripped off by other trades. Install it when you cut out the house, claim your bay, and move on to the next job knowing your work is protected. Made in USA by JT Products LLC. ## Features - THE FIRST & ONLY LINE SET ROUGH-IN BOX: Plumbers have their washer boxes. Electricians have their boxes. Now HVAC contractors have theirs. The Lineset Box gives every line set a clean, weathertight, professional rough-in at the exterior wall penetration point. Made in USA. UL-listed material. - CLAIM YOUR BAY ON DAY ONE: Install the Lineset Box when you cut out the house during rough-in. Stake your space on the exterior wall before siding contractors, landscapers, and other trades start working around your exposed copper lines. - PROTECTS COPPER LINE SETS DURING CONSTRUCTION: Copper refrigerant lines are installed at the start of construction and poke out of the exterior wall for months. Other trades bump them, bend them, kink them. One kink and it's done, hours of rework. The Lineset Box eliminates that risk. - WEATHERTIGHT TERMINATION POINT: Seals the wall penetration against air, moisture, and pests better than foam alone. Clean, architecturally pleasing finish for line set, low voltage control wiring, and condensation drain. Run your lines through or store them inside until you return to set the condensers. - FAST, SIMPLE INSTALLATION: No special tools required. Any installer can do it in minutes. Available in white and black. Constructed from UL-recognized polypropylene (UL File E130336, UL 94 HB rated). Built to last the life of the system. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0127QD39E | | Best Sellers Rank | #314,506 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #810 in Accessories (Home & Kitchen) | | Date First Available | July 21, 2015 | | Item Weight | 10.2 ounces | | Item model number | LSB01 | | Manufacturer | J.T.
