The M-D Building Products line offers adjustable aluminum and hardwood thresholds, as well as heavy-duty aluminum and vinyl thresholds, designed to seal gaps under doors and protect against drafts, moisture, dust, and insects. These thresholds are suitable for both new door installations and replacements of existing thresholds. Installation requires a hacksaw for length adjustments and, in some models, scissors for the vinyl insert. The documentation details various sizes, colors, and replacement part numbers for vinyl seals.
Adjustable Aluminum & Hardwood Threshold Features
The M-D Adjustable Aluminum & Hardwood Threshold is designed with an adjustable riser to accommodate unique and uneven gaps found under doors. This feature allows for a more effective seal, minimizing the passage of air, moisture, and pests. The product includes all necessary hardware for installation – fasteners, bolts, nuts, a cap, and screws.
This threshold can be configured for either outswing or inswing doors, providing versatility in application. The hardwood component is unfinished oak, allowing users to stain or paint it to match existing décor. Prior to installation, the threshold can be cut to the desired length using a hacksaw. For optimal sealing performance, the documentation suggests using the threshold in conjunction with a door sweep or under door seal.
Heavy-Duty Aluminum & Vinyl Threshold Specifications
The Heavy-duty Deluxe Aluminum Threshold features a vinyl seal for enhanced protection against environmental factors. Several variations of this threshold are available, differing in length, color, and specific dimensions.
Available lengths include 32 inches, 36 inches, and 72 inches. The width of all models is 3-3/4 inches, and the height is 3/4 inch. Color options include Brite Gold, Silver, Satin Nickel, Bronze, and Oak. The thresholds are constructed from heavy-duty durable aluminum and flexible vinyl.
These thresholds are designed to fit doorways up to 32 inches wide and seal a gap of 5/8 inch between the bottom of the door and the floor. The flexible vinyl feet further contribute to the sealing process by creating a barrier at the base of the threshold.
Installation Procedures
Installation of both threshold types involves similar procedures. A hacksaw is required to cut the threshold to the desired length. For the aluminum and vinyl threshold, the vinyl insert can be cut to length using scissors. All models include screws for installation.
The documentation specifically notes the availability of replacement vinyl seals. For the aluminum and vinyl threshold, M-D item number 43824 or 43826 can be used as replacements. This allows for continued functionality of the threshold even after the vinyl seal wears out.
Material Composition and Durability
Both threshold types are constructed from heavy-duty durable aluminum and flexible vinyl. This combination of materials provides both strength and flexibility, ensuring a long-lasting and effective seal. The aluminum provides structural support, while the vinyl offers a pliable barrier against drafts and moisture. The adjustable hardwood threshold utilizes unfinished oak in addition to aluminum components.
Color and Finish Options

They are suitable for both new construction and renovation projects, serving as replacements for worn or damaged thresholds. The adjustable riser on the aluminum and hardwood threshold makes it particularly useful for situations where the gap under the door is uneven or non-standard. The documentation suggests using these thresholds in conjunction with door sweeps for optimal sealing performance.
