CX-9 Criss-Cross Coil Insert – Straight
The CX-9 Criss-Cross Coil Insert – Straight is a high strength four strut insert ideally suited for precast concrete edge lift applications.
The four strut design and high safe working loads make this insert a good, safe choice for preventing panel failures.
The Criss-Cross Coil Insert – Straight is available in plain, hot dip galvanize, or stainless steel finish.
See load data below for thin slab edge and face lift.

- SWL based on 3000 psi concrete compressive strength.
- SWL includes a 4:1 safety factor.
- Inserts must have a 1/2” setback.
- Minimum edge distance apply to 2 edges only. All other edges require 2x length of the insert.
- Minimum corner distance shall be 1.5x minimum edge distance for shear when loaded towards the edge, unless noted otherwise.
- Minimum anchor spacing shall be 2 x the edge distance for tension and 3x the edge distance for shear.
