Cable Support Blocks

These block assemblies are used to separate, stabilize and support cable in a precast concrete trench or channel system. Two aluminum sleeves on either end of the block layers are screwed into the sidewalls of the trench for a secure fit. 

Many hole sizes and configurations are available. Print out the appropriate pdf drawing file from the chart below, mark up the print with your cabling requirements, and for a free quote.
