Strength Hinges & Knuckles

PRT's front and rear load lids have strength hinges and seamless knuckles that hold up to 2000 pounds each. Our one piece lids are designed to allow for hinge movement and lay flat behind the container preventing damage.

Stability

PRT front and rear lids are double-walled to provide maximum lid life. They offer center load strength while being weather and crack resistant.

Durability

PRT's special lid design offers flexibility to protect from lid crushing and prevent broken hinge rods and cracked hinge knuckles. They also are designed to maximize water run-off capacity.
