3.7 Inch J-Box Mud Plate | White | Jupiter Series | Goodlite G-37051

Achieve a flawless, high-end trimless ceiling integration with the Jupiter 3.7" J-Box Mud Plate. Registered under product code G-37051 (Ordering Code: CYD/37/TL/MP), this essential structural hardware component is specifically engineered for trimless ("spackle-in") surface or pendant cylinder applications. Designed to adapt a standard 4-inch architectural junction box down to a minimalist 3.70-inch round aperture, this plate allows drywall compound to be applied directly up to the inner rim of the fixture opening, rendering the junction point completely invisible. This round mud plate features an expanded Outside Diameter (OD) of 6.30 inches, providing a wide perforated perimeter flange that ensures optimal adhesion and bonding for joint compound or plaster. This wide outer footprint helps distribute structural tension evenly across the ceiling joint, eliminating micro-cracking around the fixture base over time. Constructed from premium heavy-gauge steel, it provides a rigid, code-compliant mounting foundation that holds the cylinder perfectly centered and flush with the finished ceiling line. Key Features: Trimless Spackle-In Integration: Conceals the hardware footprint completely by letting drywall mud feather smoothly right to the inner 3.7" aperture edge. Standard 4" J-Box Adaptation: Installs directly onto standard 4-inch round or octagonal junction boxes, converting standard rough-ins to high-end trimless cylinder configurations. 6.30" Anti-Cracking Outer Flange: The generous 6.30-inch outside diameter offers ample surface area for plaster bonding, ensuring long-term structural integrity. Heavy-Duty Rigid Steel Build: Engineered with precision structural tracking to safely align and support Jupiter 3.7-inch architectural cylinder luminaires.
