KoldLok prevents airflow bypass by closing off cable cutouts - even when cables are passing through them! The result is increased static pressure in the underfloor plenum and more cold air getting to where you want it to go.

KoldLoks can pay for themselves in less than a year by reducing your air conditioning load or by mitigating the need for additional cooling capacity!

Significant discounts are available for quantities of 10 or more.  Installation is available.
