Coastal Hardware Store is an authorized Sure-Loc dealer. Current products are offered in passage, privacy, keyed entry, dummy, handleset-trim, and select keyed-entry-with-deadbolt configurations, with additional half-dummy and double-dummy options represented in the collection.

Why Choose Sure-Loc Door Knobs?

Sure-Loc offers knob hardware across several design families, giving shoppers options for both interior rooms and compatible residential entry doors. The right knob depends on the required function, door preparation, backset, material, finish, and preferred style.

• Multiple door functions: The current collection includes passage, privacy, keyed entry, dummy, handleset trim, and select entry-and-deadbolt combination configurations.
• Traditional and modern designs: The assortment ranges from classic ball, tulip, mushroom, and egg-shaped knobs to cleaner contemporary designs with round and square rosettes.
• Sure-Loc Modern options: Bergen and Zurich knob families provide contemporary styling with round or square trim and several current finish choices.
• Ridgecrest options: Zermatt, Oakley, Slickrock, and other Ridgecrest designs add solid-knob, sideplate, and specialty configurations with their own preparation requirements.
• Multiple current finishes: The live collection includes Flat Black, Polished Brass, Polished Chrome, Satin Brass, Satin Nickel, Satin Stainless Steel, and Vintage Bronze.
• Coordinating hardware: Sure-Loc offers matching or complementary levers, deadbolts, handlesets, and other door hardware for projects that use a consistent finish or product family.

Types of Sure-Loc Door Knobs Available

Passage Door Knobs

Passage knobs operate the latch without providing a locking function. They are commonly selected for hallways, closets, pantries, laundry rooms, and other interior doors where privacy or keyed security is not required. Passage is one of the most widely represented functions in the current Sure-Loc collection.

Privacy Door Knobs

Privacy knobs provide an interior locking function for bedrooms, bathrooms, and similar rooms. Lock operation varies by family. Current Sure-Loc products include push-button, push-pin, and finger-turn privacy mechanisms depending on the selected knob, so review the operating details for the exact model.

Keyed Entry Door Knobs

Keyed entry knobs provide exterior key access and an interior locking control for compatible residential openings. Current Sure-Loc families such as Bergen, Zurich, Juniper, Tahoe, Arapaho, and others offer keyed-entry configurations. Keyway, latch, keying options, and door requirements can differ by model.

Dummy Door Knobs

Dummy knobs are inactive trim used where an operating latch is not required, such as some closets, inactive double doors, and decorative applications. Current collection filters include dummy, half-dummy, and a double-dummy configuration. Confirm whether the selected product provides trim on one side or both sides of the door.

Handleset Interior Trim

Several Sure-Loc knob families are available as interior trim for compatible exterior handlesets. These products are not complete standalone knob locksets. They provide the inside knob and trim needed to coordinate with the corresponding handleset, so confirm the exterior hardware and compatibility before ordering.

Entry Knob & Deadbolt Combination Sets

The current collection includes selected knob-and-deadbolt combinations, including Arapaho and Tahoe configurations. These sets combine a keyed entry knob with a coordinating deadbolt and can simplify finish and key coordination on compatible entry doors. Verify the included components, door preparation, and keying arrangement for the exact set.

How to Choose the Right Sure-Loc Door Knob

Start with the required function and existing door preparation, then compare knob shape, rosette style, backset, door thickness, finish, and keying requirements. Sure-Loc's different product families do not all use identical specifications.

• Choose the correct function: Determine whether the door needs passage, privacy, keyed entry, dummy, handleset trim, or an entry-and-deadbolt combination.
• Check the backset: Many standard Sure-Loc knobs use an adjustable 2-3/8-inch to 2-3/4-inch backset. Several Ridgecrest products, including Zermatt, Oakley, and Slickrock, require either 2-3/8-inch or 2-3/4-inch backset to be specified.
• Measure the door thickness: Many current knobs fit 1-3/8-inch to 1-3/4-inch-thick doors. Some entry configurations use different ranges, so follow the specifications for the selected product.
• Compare knob shape: Current choices include round, mushroom, tulip, egg-shaped, and more contemporary solid-knob designs. Consider both appearance and how the knob feels in everyday use.
• Choose the rosette style: Bergen, Zurich, Durango, Zermatt, and other families include round or square trim options in the current assortment.
• Review keying requirements: Several current Sure-Loc entry knobs can be keyed alike in sets of four. Keyway and keying capabilities vary by family, so verify compatibility when multiple locks need to operate from the same key.
• Coordinate the finish: Use Sure-Loc's exact finish designation when matching knobs with handlesets, deadbolts, levers, and hinges rather than assuming similar finish names are identical.

Materials, Styles & Finishes

Construction varies across the Sure-Loc knob collection. Sure-Loc identifies Juniper as a hollow mushroom-shaped formed-brass knob, Tulip as a hollow formed-brass knob, Tahoe as a hollow ball knob made from formed brass, and Arapaho as a hollow egg-shaped formed-brass design. Ridgecrest's Slickrock is specifically identified as a solid-brass knob, while other Ridgecrest products use different materials and constructions.

The current Coastal Hardware collection includes Flat Black, Polished Brass, Polished Chrome, Satin Brass, Satin Nickel, Satin Stainless Steel, and Vintage Bronze. Availability varies by knob family. For example, Bergen is offered in several modern finishes, while Tulip currently has a more limited selection.

Finish characteristics and warranty treatment also differ. Sure-Loc identifies Vintage Bronze as a living finish whose oxidized surface can wear naturally with use. Flat Black and Satin Brass have different finish-warranty terms from the manufacturer's standard finish coverage.

Featured Sure-Loc Door Knob Styles

The current collection includes Sure-Loc, Sure-Loc Modern, and Ridgecrest knob families with different shapes, rosettes, materials, functions, and installation requirements.

• Bergen: A Sure-Loc Modern knob offered with round and square rosettes. Current functions include passage, privacy, keyed entry, dummy, and handleset interior trim.
• Zurich: A contemporary solid-knob design available with round and square trim. Current configurations include passage, privacy, keyed entry, dummy, and handleset trim.
• Zermatt: A Ridgecrest solid-knob family offered in standard and square-rosette versions. Standard passage, privacy, and dummy functions are available, with keyed entry handled through a separate sideplate configuration.
• Juniper: A hollow mushroom-shaped formed-brass knob available in passage, privacy, entry, dummy, and handleset-trim configurations.

• Slickrock: A solid-brass Ridgecrest knob with passage, privacy, dummy, double-dummy, and entry-with-deadbolt configurations.

Installation & Compatibility

Many current Sure-Loc knob families are designed for common residential tubular door preparations. Juniper, Tahoe, Tulip, Bergen, and other standard products use an adjustable 2-3/8-inch to 2-3/4-inch backset and generally fit doors from 1-3/8 inches to 1-3/4 inches thick.

Those specifications should not be applied to every knob. Ridgecrest models such as Zermatt and Oakley require either a 2-3/8-inch or 2-3/4-inch backset to be specified rather than using the same adjustable latch. Slickrock also uses a specified backset and lists a different door-thickness range for its entry configuration than for its interior functions.

Before replacing existing hardware, verify the face bore, edge bore, backset, door thickness, latch faceplate, strike, rosette footprint, and function. Matching the general size or finish of the old knob does not guarantee that a new lockset will use the same preparation.

Shipping & Warranty Information

• Shipping: Current Sure-Loc door-knob products generally fall under Coastal Hardware Store's standard manufacturer lead time of approximately 5-7 business days unless another estimate appears on the individual product page. Orders of $100 or more qualify for free standard ground shipping within the contiguous 48 states and District of Columbia. Keying requests can add processing time. View Shipping Policy.
• Warranty: Sure-Loc publishes a lifetime mechanical warranty against manufacturing defects for the original user while occupying the premises where the hardware was originally installed, subject to the manufacturer's exclusions. Standard finishes generally carry five-year finish coverage, while Flat Black and Satin Brass carry two-year finish coverage. Vintage Bronze and Oil-Rubbed Bronze are living finishes, and normal wear of their oxidized coatings is excluded from finish coverage.
