BackIt®

BackIt® provides a solid backing solution to support handrails, wall-mounted shelving, and other equipment. Installation is greatly simplified through a simple screw connection to the stud flange, delivering a flexibility for use in 12”, 16”, and 24” stud spacing. Shelf tabs hold a variety of wood backing sizes and shapes, including 1” x 6”, 2” x 4”, and 2” x 6”, in place during installation. BackIt exceeds code-required allowable load resistance of 250lbs in the vertical and horizontal directions.
Features
  • Guide holes for stud and wood attachments
  • Shelf tabs to rest wood upon during installation
  • No pre-determined stud layout
  • May be used with multiple sizes of wood
  • Resists load in the directions recommended by codes

BackIt® Applications

The unique design of MasterClip allows it to be installed either as a vertical deflection connection or a rigid connection.  Attachment to the primary structure may be made with a PAF, screw/bolt anchors, or weld and is dependent upon the base material (steel or concrete) and the design configuration.

BackIt - Wall Backing

Solid Wall Backing for Handrails, Shelving, & Wall Mounted Equipment

Installation Instructions

  1. Place clip flush against wall stud flange and attach to stud with required amount of approved fasteners. Fastener amounts may vary by application.
  2. Rest wood piece on shelf legs and attach to clip with required number of screws through guide holes. For higher loads, attach BackIt to the stud web through a guide hole in the interior leg.

Allowable Loads

The recommended allowable loads and moments reported in this table are for the clip and attachment to the stud only. The attachment to the backing material must be designed by a design professional.

IBC (International Building Code) and OSHA (Occupational Safety and Health Administration) load requirements include the ability of wall backing to resist a minimum of 200lbs of concentrated load, or 50lbs per linear foot in any direction. BackIt® satisfies the load requirements in vertical (F3) and horizontal (F2) directions. Extra testing has been done in the rotational (M1) direction. Product test reports are available upon request. Contact TSN Technical Support at (888) 474-4876 for more information.
