Miscellaneous
The ICFVL Ledger Connector System is engineered to solve the challenges of mounting
wood or steel ledgers to insulated concrete form (ICF) walls. The ICFVL is designed to provide
both vertical and lateral, in-plane performance. There are many benefits over traditional anchor
bolting, including better on center spacing in most cases, faster installation and no protrusions.
The embedded legs of the ICFVL are embossed for additional stiffness and the hole
allows for concrete to flow through and around the connector. The exposed flange on the
face of the ICF provides a structural surface for mounting either a wood or steel ledger.

Typical Steel Ledger
Installation with ICFVL
(minimum 16 ga steel ledger)
Requires 4 screws
at each location.
Table provides on
center spacing.
1. The Designer may specify different spacing based on the load requirements.
2. Spacings are based on perpendicular to grain capacity of bolt in wood ledger compared to tested value of ICFVL.
Additional connectors required for out-of-plane loads.
3. See flier F-ICFVL for additional connection details.
4. For steel ledgers, the 68 mil ledger spacing is closer than the 54 mil ledger because the calculated load of
a bolt is higher in a thicker piece of steel.
5. Steel ledger values are based on steel. F
u
= 60 ksi.
6. Maximum ICF foam thickness is 2

These tables address vertical load applications only.

1. Fasteners for wood ledger (ICF-D3.62) are provided with
the part and fasteners for steel ledger are not provided.
2. Loads apply to ICF foam thicknesses of 2

4. Tabulated loads may not be increased.
5. Concrete f'c = 2500 psi minimum.
6. When combining download and lateral loads,
Designer shall evaluate as follows:
Design Download/Allowable Download + Design
Lateral Load/Allowable Lateral Load ≤ 1.
7. The ICFVL must be installed no closer than 4" below
the top of the wall to achieve the allowable loads
shown. For installations where the ICFVL is installed
less than 4" from the top of the wall (including flush
applications) multiply the allowable loads by 0.94.
