Prime-Line J 4602 4 in Floor Stop Brushed Chrome - Secure Door Hook

In this review the Prime-Line J 4602 4 in floor stop is evaluated for use on commercial and heavy residential doors; the bottom line is that it is a simple, durable solution when door stability and secure floor mounting matter most. The reviewer found the solid brass construction and brushed chrome finish make it both sturdy and attractive, and the built-in hook holds the door reliably. Installation is straightforward for anyone comfortable with basic tools, and the 3-hole base gives confidence that the stop will stay put under repeated use.

Key Features

• Solid brass construction: Provides long-term durability and resists deformation under the stress of heavy doors.
• Brushed chrome finish: Offers a neat, low-gloss look that blends with commercial and modern interior hardware.
• Built-in hook: Keeps the door held securely in the open position to prevent unwanted movement or drafts.
• 3-hole mounting: The three mounting holes distribute load and provide a more secure installation on floors that see heavy traffic.
• Rubber bumper: Cushions contact to protect both the door and the stop while reducing noise on engagement.
• Includes lag screws: Hardware is provided for floor mounting so installation is straightforward without a separate trip for fasteners.

Who It's For

This floor stop is best suited to facilities managers, contractors, and homeowners who need a reliable hook-mounted stop for out-swinging or heavy doors in offices, schools, or other commercial settings. It performs well where repeated holding of a door in an open position is required and where a low-profile, finished look is desired.

Those who should look elsewhere include users who need a recessed or adjustable stop, or who cannot drill into the floor; also, if a magnetic hold or very heavy-duty industrial anchoring is required, a different specialized product may be more appropriate.

Pros & Cons

Pros

Cons

• Some customers report mixed feelings about the included hardware quality, so higher-grade fasteners may be desired for certain floor types.
• Mounting requires drilling into the floor, which may not be suitable for all settings or surfaces.
