TNT Covers
"Other pit covers cannot handle the weather and abuse they constantly face, this means many expensive and unnecessary service calls and repairs.  TNT Covers are designed to provide superior support for ventilation fans for the life of the cover."  Kerry Nicolaus, CEO Site Maintenance Solutions 

Quality Materials  

TNT Covers are made from green-treated lumber, stainless steel screws, and 1/4" thick High Density Polyethylene (HDPE) sheeting.  4x4s are used for external framing to minimize the damage caused by removal and installation of the cover during agitation and pumping of the pit.  2x4s are used for internal framing to provide support for the ventilation fan.  Many competitor products have no center support, resulting sagging and misaligned fans. 

Durable Craftsmanship

TNT Covers are securely assembled using standard framing techniques.  The perimeter 4x4s are notched to provide added strength.  The center support framing is built specifically to support standard fan flanges. 

Custom Fit Design

Each TNT Cover is built exactly to specific pit dimensions provided by the site owner or manager.  Each pit should be measured individually to ensure proper mounting and seal.

TNT Cover Additional Benefits

Quality manufactured TNT Covers provide improved ventilation as a result of a proper pit seal.  Safety is improved for site maintenance technicians who must perform routine maintenance on ventilation fans.  TNT Covers provide the strength necessary to suppport significant snow accumulation common to the upper Midwest.
