The ICFVL ledger connector system is engineered to solve the challenges of mounting wood or steel ledgers to insulated concrete form walls. The ICFVL is designed to provide both vertical and lateral in-plane performance. The system offers many benefits over traditional anchor bolting, including better on-center spacing and faster installation with no protrusions.
The embedded legs of the ICFVL are embossed for additional stiffness. The hole enables concrete to flow through and around the connector. The exposed flange on the face of the ICF provides a structural surface for mounting a wood ledger.
ICFVL in ICF
- For use with a minimum 4″-thick core
- Snap a chalk line for the bottom of the ledger
- Mark required on-center spacing
- Use ICFVL to mark kerf locations
- Cut kerfs as marked
- Insert ICFVL flush to the face of the ICF
- Pour concrete
Wood Ledger Attachment — ICFVL-W or –CW
- Slip appropriate ledger connector underneath the ledger
- Install the eight ICF-D3.25 screws partially into the ledger
- ICF-D3.25 installs best using a low-speed drill with 3/8″ hex-head driver
- For denser wood species (specific gravity ≥ .50), predrilling may be necessary
- Predrill ledger only with 5/32″ drill bit
- Position bottom of the ledger level to the chalk line and drive the screws through the wood and into the ICFVL
Steel Ledger Attachment
- Position bottom of the ledger level to the chalk line and against the ICFVL
- Attach with four #14 x 3/4″, #3 drill-point screws (not provided)
- All screws should be located at least 1/2″ from the edge of the ICFVL
- Space screws evenly
