ICFVL® Ledger Connector System for Wood Ledger
Product Details
The ICFVL-W/ICFVL-CW is designed to be used with the ICFVL ledger connector system for mounting wood ledgers to insulated concrete form (ICF) walls. The ICFVL-W is to be used when using single 2x ledger sizes. The ICFVL-CW is to be used when using single LVL ledger sizes.
Key Features
- A carton of ICF-D3.25 screws (128 QTY) is included with ICFVL-W and ICFVL-CW carton sales and is also sold separately
- ICFVL-W has a flange width of 1.56" to accommodate a single 2x ledger size
- ICFVL-CW has a flange width of 1.81" to accommodate a single LVL ledger size
Material
- 16 ga. (54 mil)
Finish
- Galvanized (G90)
Installation
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 in dry conditions, using a low-speed drill with a 3/8" hex-head driver
- For denser wood species (specific gravity ≥ .50), predrilling may be necessary; predrill ledger only with a 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
Warning
- Industry studies show that hardened fasteners can experience performance problems in wet environments. Accordingly, use this product in dry environments only.

| Allowable Loads (lb.) — ASD | |
|---|---|
| Vertical (F4) | Lateral (F1) |
| 2,280 | 1,265 |
- Use (8) ICF-D3.25 screws provided with ICFVL-W or ICFVL-CW
- Loads apply to ICF with 4 1/2" maximum foam thickness with the ICFVL8 and 3 1/4" maximum foam thickness with the ICFVL6.
- Loads assume a minimum spruce-pine-fir ledger.
- Loads may not be increased for short-term loading.
- The top of the ICFVL must be installed 4" minimum below the top of the wall. For installations where the ICFVL is installed less than 4" from the top of the wall (including flush), multiply the allowable loads by 0.94.

- This table addresses vertical load applications only.
- The Designer may specify different spacing based on the load requirements.
- Spacings are based on perpendicular to grain capacity of bolt in sprucepine-fir wood ledger compared to tested value of ICFVL with a maximum allowable spacing of 48".
- Connector spacing requirements are based on a CD = 1.00 load duration. Contact Simpson Strong-Tie for alternate load durations.
- Bolt design values are based on 2015 NDS Table 12E for SPF lumber (SG = 0.42), a minimum 6" anchor embedment, and concrete with f'c = 2,500 psi.

| Values in the cells highlighted in yellow represent the maximum allowable spacing of 48". | ||||||||||||
- Values shown are maximum spacing distances (inches) based on two-span ledger and simple supported joists. It does not consider concentrated loads. The Engineer of Record can modify the spacing accordingly for other conditions.
- Joist and ledger are to be designed by others.
- Spacing tables address vertical load applications only. If the connection is designed to resist simultaneous lateral loads, spacing may decrease. Contact Simpson Strong-Tie for additional information.
- The ICFVL must be installed no closer than 4"below the top of wall to achieve the connector spacing.
- The maximum distance between the end of the ledger and the first ICFVL is 12" as per the recommended splicing installation.
