Tapered Bolts – Uniquely designed tapered bolts at both the bottom and the top of the system engage with ease.
Strike plates with rollers – Strike plates with rollers add forgiveness, so if install isn’t perfect or a home settles over time, the bolts stay aligned.
Handleset latch – While the deadbolt secures the tapered bolts, the handleset engages the latch.

The Masonite Performance Door System is made with premium components that are designed to work together – which means no more leaks or drafts. Choose a superior exterior door with premium fiberglass construction, a rot-resistant frame and 4-Point Performance Seal. The Masonite Performance Door System is 64% better at keeping air and water out than the leading competitor, which means no more leaks or drafts.

Square edge door – A square edge door fits perfectly into its frame for a solid, energy efficient seal. Other doors have rounded proud edges that create gaps.

Self-adjusting sill – A self-adjusting sill maintains its seal, adapting to imperfect or changing conditions. Other sills need to be manually adjusted.
Adaptive weatherstripping – Adaptive weatherstripping is made of high-end, low-wick memory foam that snaps back into shape, while others crumble and become ineffective.

Enhanced corner pads – Enhanced corner pads stop upward water pressure and form a tight seal between sill, door panel and frame. Other designs don’t compare.

Rot-resistant frame – Our rot-resistant frame never wicks water, swells or molds. They are immune to both the heat and cold, providing quality and durability.

Fiberglass construction – Premium fiberglass doors don’t rot, warp or crack, making them virtually weatherproof. They come in a variety of styles, too.
