STILEChoice® Edge Advantage

The MDF hinge edge is positioned at a 90° angle, creating a robust mounting surface for hardware that won't split like traditional wood. While talk is cheap, our doors underwent an independent slam test, enduring over 519,000 slams—surpassing the commercial Heavy Duty standard—before we concluded the test.

At IHS Door Company, we went even further by conducting additional tests. One involved simulating the removal of hinge screws on the job: we hung the test door, removed the screws twice, and reinstalled them before starting the slam test. After 100,000 slams, we removed and reinstalled the screws again, successfully completing an extra 25,000 slams before deciding to stop.
