Continuous Hinges: The Industrial Solution for Door Longevity
When standard butt hinges fail under the stress of high-traffic or heavy-duty doors, continuous hinges provide the ultimate structural reinforcement. Unlike traditional hinges that concentrate door weight on two or three points, a continuous hinge distributes the load across the entire height of the door and frame. We carry the industry’s most trusted brands—ABH Mfg, Pemko, Hager, McKinney, and Select—offering a "fit-and-forget" solution that prevents door sag and extends the life of the opening. Available as Aluminum Geared or Stainless Steel Pin-and-Barrel types, these continuous hinges are the gold standard for schools, hospitals, and storefronts.
Engineered for ANSI/BHMA Grade 1 performance, our selection of continuous hinges is designed to withstand millions of cycles in the most demanding environments. Whether you are retrofitting a damaged frame or specifying hardware for new construction, these hinges provide unmatched security and privacy by eliminating the gap between the door and the jamb. From full-surface models that hide frame damage to swing-clear options for ADA compliance, our catalog features the precise engineering of Select, Hager, and ABH to ensure your doors stay aligned and operational for decades.
Aluminum Geared Hinges
Aluminum geared hinges utilize a unique interlocking gear design that provides exceptionally smooth operation for heavy doors. Extruded from high-strength aluminum and anodized for corrosion resistance, these hinges—from brands like ABH Mfg, Pemko, and Hager—are the preferred choice for high-traffic retail storefronts. Their design eliminates stress on the fasteners, preventing the door from sagging over time.
Stainless Steel Pin & Barrel
For the most extreme security and industrial environments, stainless steel pin-and-barrel hinges offer maximum strength. Constructed from 14-gauge 304 stainless steel, these hinges from ABH, Markar, and McKinney are ideal for high-abuse areas like detention centers or hospital trauma rooms. They provide a high degree of fire protection and are resistant to tampering and heavy impacts.
Concealed
Designed for a sleek, architectural finish, concealed continuous hinges are mounted between the door edge and the frame rabbet. When the door is closed, the hinge is entirely hidden from view, providing a clean aesthetic and superior tamper resistance. This is the standard choice for new construction in schools and office buildings using Pemko or Select geared hinges.
Full Surface
Full-surface continuous hinges are the go-to solution for retrofit and repair. The hinge leaves are mounted to the face of the door and the face of the frame, allowing you to bypass stripped screw holes or damaged hinges. This mounting style is highly visible and provides an industrial look while offering massive reinforcement to weakened frames.
Half Surface
Half-surface hinges are versatile "problem solvers" where only the frame leaf is mortised or hidden. The door leaf is mounted to the face of the door, making it ideal for retrofitting existing frames where the door has been replaced or the door edge is damaged. These are commonly used to reverse the swing of a door without intensive frame modification.
Half Mortise
Half-mortise hinges feature one leaf that is surface-applied to the frame and another that is hidden in the door edge. This configuration is often used on wood doors with hollow metal frames, providing a secure, high-strength pivot point while maintaining a relatively clean appearance from the pull side of the opening.
Swing Clear
Swing-clear continuous hinges are specifically engineered for healthcare and ADA-compliant applications. These hinges swing the door completely out of the opening at a 90-degree angle, maximizing the clear width for gurneys, wheelchairs, and large equipment. ABH and Pemko swing-clear models are essential for meeting stringent hospital fire and accessibility codes.
Replacement Screw Packs
A continuous hinge is only as strong as its fasteners. We provide replacement screw packs for geared and pin-and-barrel hinges from ABH, Pemko, Select, and Hager. Whether you are retrofitting a hollow metal frame or a solid wood door, using the correct high-strength hardware is critical to preventing door sag.
- Machine & Wood Screws: We stock 12-24 undercut machine screws for metal frames and deep-thread wood screws for maximum pull-out resistance in solid cores.
- Phillips & TORX Drive: Choose standard Phillips for universal serviceability or TORX (6-lobe) security screws to eliminate "cam-out" and provide superior tamper resistance in high-traffic or high-security areas.
Continuous Hinge Parts
Maintaining high-traffic openings often requires more than just new fasteners. Our inventory of continuous hinge parts includes essential components for ABH, Pemko, Hager, and Select hinges to keep your doors operating smoothly and looking professional. Replacing worn or damaged parts is a cost-effective way to restore the security and aesthetic of your entrance without the labor of a full hinge replacement.
