ETB Hidden Connector Kit
On This Page
The ETB hidden connector provides a load-tested beam connection without any visible hardware. Interlocking plates are fastened onto each member and lock together for a secure structural connection.
- Faster than other time-consuming methods and requires removal of less beam material
- Three sizes address common beam sizes from 4x6 through 6x12
- Connector can be routed into the beam end for a completely flush installation
- Templates available to make accurate installation more efficient
- Plates — Aluminum 6082-T6
- Plates — none; screws — Dacromet® corrosion-resistant coating
- Use all specified fasteners; see General Notes.
- Rout a 3/8" (10mm) deep pocket into the side of the supporting beam as shown for the lower plate.
- Install lower plate with 16d hot-dip galvanized nails (not included in kit).
- Install horseshoe plate onto end of supported beam using SCRB screws supplied in kit. Screws are installed at a downward angle (approx. 45°).

Dimensional and Fabrication Information
Factored Resistance Table (Limit States Design Values)
- Factored resistances assume standard term load duration; reduce value where other load durations govern. Do not increase value for short-term load duration.
- Factored resistances have been calculated in accordance with CSA O86-14 assuming dry service condition (KS = 1.00) and seasoned lumber (moisture content ≤ 15%) at time of fabrication. For unseasoned lumber (moisture content > 15%) multiply tablulated values by 0.80. For wet service condition multiply tablulated values by 0.67.
- Do not use ETB connectors with preservative-treated woods.
- Factored resistances shown are the lower of the test value, the fasterner capacity or the effective shear capacity of the joist assuming joist and headers are same species.
- Substitution for fasteners is not permitted. All fasteners must be used as specified.
- Nails: 16d HDG = 0.162" dia. x 3 1/2" long hot-dip galvanized.
