ICFLC Ledger Connector System

The ICFLC, & ICFLC-W ledger connector system is engineered to solve the challenges of mounting steel or wood ledgers on insulated concrete form (ICF) walls.
Simpson's ledger connector system is easy, quick and versatile to use.
The perforations in the embedded leg of the ICFLC permit the concrete to flow around it anchoring the ICFLC securely within the concrete.
The exposed flange provides a structural surface for mounting either a wood or a steel ledger.
Minimum steel ledger specification is A-653 SQ Grade 50.
No load duration increase is allowed.
Spacing is based on vertical load only.
For steel ledger, spacing is based on a combination of ledger gauge and anchor bolt diameter.
Spacing is closer for a 14 gauge ledger in order to achieve the equivalent bolt/ledger capacity.
Minimum concrete compressive strength (F'c) is 2500 psi.
The designer may specify different spacing based on the load requirements.
Allowable lateral capacity, parallel to the ledger and ICF wall, is 200 lbs at 1/8" deflection with no increase allowed.
Use interaction equation for combined lateral and vertical loading to be less than 1.0.
Some ICF systems may allow horizontal installation of the ICFLC to achieve higher lateral loads in addition to the ICFLC installed for the vertical loads.
