About Stair Tread Covers and Nosing
More
Stair Tread Nosing for Wet Concrete
This nosing has an integral anchor for installation in fresh concrete stairs; no additional fasteners required. Construction adhesive (sold separately) is for use between nosing and the front edge of the stair to prevent cracks.
Style B are durable to handle heavy traffic and rough environments. Nosing is embedded with abrasive grit for traction.
Floor Drain Grates
Use these drain grates in areas without vehicle traffic.
Heavy Duty Floor Drain Grates
These grates are strong enough to handle a high volume of traffic, even from vehicles.
Iron Floor Drains
Two-piece drains clamp together with the included fasteners.
Unthreaded drains require caulk or a clamp to install. Drains that require caulk fit over the drainage pipe. Attach them with lead caulk (not included). Drains that require a clamp use a pipe coupling (not included) to install.
Style C have an adjustable-height, threaded drain grate.
Style D have a hinged grate that lifts open for easy cleaning.
