The MantelMount RB100 Recess Box Kit is an accessory designed to be used with specific MantelMount models (MM340, MM540, MM700, MM710, MM720) to allow for a recessed installation of the television mount. This addendum serves as a replacement for certain steps in the standard MantelMount Installation Manual, specifically Steps 1.5, all of Step Two (Determine Wall Placement), and Step Three (Attach Mount to Wall). It is crucial to use this addendum in conjunction with the main installation manual, completing all steps from the manual unless explicitly replaced by this document. Users are advised to read both the entire Installation Manual and this Addendum thoroughly before beginning the installation process.

Function Description:

The primary function of the RB100 Recess Box Kit is to enable a flush-to-wall installation of compatible MantelMounts. By recessing the mount into the wall, it provides a cleaner, more integrated aesthetic, reducing the projection of the mount and TV from the wall when in the stowed position. This kit modifies the installation process to accommodate the recess box, which houses a significant portion of the mount's mechanism within the wall cavity. It is designed to work with both custom-built wall studs and standard wall stud configurations, offering flexibility in installation. The recess box also incorporates features to manage cable routing and ensure proper functionality of the MantelMount's lowering and swiveling actions.

Important Technical Specifications:

• Compatibility: Designed for MantelMount models MM340, MM540, MM700, MM710, MM720.
• Recess Box Dimensions (Cutout Size):
  • Width: 7.4 inches (188mm)
  • Height: 28.2 inches (717mm)
• Recess Box Depth: 3.7 inches.
• Overall Dimensions (Recess Box):
  • Thickness: 1.75 inches (flange thickness)
  • Maximum Drop: 27.0 inches
  • Minimum Clearance: 12.0 inches
  • Maximum Clearance: 16.0 inches
• Wall Stud Requirements:
  • Custom Built Wall Studs: Requires new wall studs to fit the exact dimensions of the Recess Box. The stud opening is 716mm tall and 187mm wide. The Recess Box is installed using wood screws (not included), with at least six screws per inner side and two per top and bottom flanges.
  • Standard Wall Studs: The Recess Box attaches to Recess Braces {63} which span horizontally to reach nearest studs. Braces are attached to studs with Lag Bolts. Drywall opening is cut using an included cardboard template. Longer Braces are available if existing studs are too far apart.
• Wall Covering Thickness: Pre-drilling for lag bolts requires a 7/32" drill bit to a depth of 2.5 inches (65mm), including wall covering. Wall covering (drywall) must not exceed 5/8" thickness.
• Mantel Depth Reduction: Installation with the Recess Box will reduce the maximum allowable mantel depth depending on the MantelMount model:
  • MM340, MM540, MM720: Maximum Mantel Depth reduced to 15 inches.
  • MM700, MM710: Maximum Mantel Depth reduced to 12 inches.
• Vertical Brace Placement: Vertical Braces {31} must be mounted between 7 and 10 inches from the bottom of the TV (or soundbar if used) to hide the bottom of the Recess Box.
• Parts Included (RB100 Addendum Kit):
  • Washer M8 {11} x4
  • Round Head Screw M8 x 16 {14} x4
  • Round Head Screw M6 x 10 {15} x2

• Additional Components Required (Sold Separately/Not Included):
  • SSB40 Adapter Plate (for MM340 and MM540 models).
  • Wood screws (for custom stud installation and attaching cut stud ends to recess box).
  • Lag Bolts (included with MantelMount MM340-MM540 for standard wall stud installation).

Usage Features:

• Recessed Installation: Allows the MantelMount to be installed flush with the wall, providing a sleek, integrated look.
• Reduced Projection: Minimizes the distance the TV and mount project from the wall when in the stowed position.
• Compatibility with Existing Studs: Offers an installation option for standard wall stud configurations using horizontal Recess Braces.
• Custom Stud Option: Provides instructions for installing new wall studs to perfectly frame the Recess Box for a highly customized setup.
• Cable Management: Includes provisions for routing cables, ensuring they are not pinched or damaged during the mount's operation. Cable Tie Anchors {22} are inserted into the Lifting Arm, and Cable Ties {24} are used to secure cables, allowing for the mount's full range of motion.
• Adjustable Placement: The installation guide provides detailed tables (Look-Up Tables) to determine the minimum distance between the mantel and the bottom of the cutout opening, based on mantel depth and vertical brace placement, ensuring proper clearance for the TV's movement.
• Brace Covers: Paintable Brace Covers {64} are included to conceal the Recess Braces {63} for a finished look that can match the wall color.
• Tilt Functionality Note: It's important to note that the tilt function of the MantelMount will only work when the mount is pulled away from the wall or in the down position. When returning the mount to the stowed position, the tilt should be brought back to a neutral upright position to avoid hitting the wall. The Recess Box also reduces the amount of side-to-side swivel when the mount is in the stowed position.

Maintenance Features:

• The manual emphasizes careful installation to prevent damage or injury.
• It advises against over-tightening Lag Bolts {17} to prevent property damage.
• Users are warned not to cut or damage fireplace components during installation, as this can lead to dangerous gas leaks. Professional consultation is recommended if uncertain.
• The document highlights that MantelMount is not responsible for damage or injury caused by incorrect installation or improper use, underscoring the importance of following instructions carefully.
• For missing/damaged parts or questions during installation, customer support is available via phone and email, indicating a commitment to assisting users with proper setup.
