JBA Junior Bent Hanger

JBA

On This Page

The JBA is a top-flange hanger for solid sawn lumber applications. This cost-effective hanger is designed to support light-to-medium loads while providing uplift. The JBA also features optional triangular nail holes for maximum nailing to increase allowable loads.

Key Features

  • Unique two-level embossment provides added stiffness to the top flange
  • Nail locations that enable effective use with nailers
  • Additional load rating for a 2x or 3x nailer
  • Engineered with increased uplift loads for earthquake or high-wind loading

Material

  • 18 gauge

Finish

  • Galvanized

Installation

  • Use specified fasteners; see General Notes and nailer table notes.
  • Ledgers must be evaluated for each application separately. Check top-flange dimension, nail length and nail location on ledger.

  1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  2. Uplift loads are based on DF/SP lumber. For SPF/HF, use 0.86 x DF/SP uplift load.
  3. Uplift loads are based on DF/SP. For SPF/HF, use 0.86 x DF/SP Uplift Load for products requiring nails and 0.72 x DF/SP Uplift Load for products requiring screws.
  4. Where noted for single-ply joist hangers, use (6) 0.148" x 1 1/2" nails.
  5. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.

Nailer Table

JBA Nailer Table
  1. Uplift values are for DF/SP nailers only. Refer to technical bulletin T-C-NAILUPLFT for SPF values.
  2. For joist members 2 1/2" or wider, 0.162" x 2 1/2" joist nails should be installed for additional uplift loads on the 3x and 4x nailer applications of 970 lb. and 1,010 lb. respectively.
  3. See technical bulletin T-C-NAILUPLFT for increased uplift loads with alternative nailing.
  4. Attachment of nailer to supporting member is by the designer.
