Made in the USA from UL-listed polypropylene, it offers a weathertight, pest-resistant seal and a clean, professional finish. Easy to install without special tools, it safeguards your work from construction damage and claims your installation space early, ensuring a flawless HVAC setup every time. ## 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. Review: Amazing & Super Clean Look - Used these black line set boxes on a new construction product. The line set boxes can be installed inset or outset and have a 1/2" lip to accommodate outset / inset applications. I used these on a project with a 3/4" rainscreen furring strip over 7/16" sheathing and 3/4" nickel gap t&g siding. The result was an air & watertight application that left the line set penetrations looking super clean and beyond professional. Would highly recommend and will not be buying anything but these for HVAC line sets. Review: Worked Great - Large enough to accommodate the line sets for a 5 zone mini-split system. Very easy to install before siding, just cutout an opening, screw to the wall and tape/seal around it. Probably much more difficult to install after siding is on. ## 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 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #415,509 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #835 in Air Conditioner Parts & Accessories | | Color | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (74) | | Date First Available | July 21, 2015 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 10.5 ounces | | Item model number | LSB01 | | Manufacturer | J.T. products, Inc. | | Material | Polypropylene | | Part Number | LSB01-BL | | Product Dimensions | 4.25 x 5.5 x 10.75 inches | | Special Features | Easy Installation | ## Images ![Lineset Box™ Line Set Rough-In Box (Black) — HVAC Exterior Wall Termination Point for Refrigerant Lines, Condensation Drain & Low Voltage Wire — Made in USA - Image 1](https://m.media-amazon.com/images/I/612uoeoh84L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing & Super Clean Look *by T***D on January 24, 2025* Used these black line set boxes on a new construction product.
