The Concealed Fix Ringed Mortice Knob (frequently referred to as a “Reeded” or “Beehive” knob) represents the pinnacle of “Period-Modern” hardware. By marrying the iconic concentric ring design of the Regency era with a contemporary snap-on rose system, this knob provides a classic aesthetic entirely free from unsightly screw heads.
Forged from high-density metals and finished in choices ranging from Antique Brass to Polished Chrome, this Concealed Fix Ringed Mortice Knob is engineered for homeowners who demand historical character without compromising on a clean, minimalist installation.
The ringed design was originally popularized in the late 18th century for its tactile superiority. Today, the addition of Concealed Fixings transforms this traditional staple into a high-end architectural component.
-
Enhanced Ergonomic Grip: The concentric rings are precision-machined into the face of the knob. These “reeds” provide subtle friction, making the knob exceptionally easy to turn—even on heavy, solid-wood doors—providing a more secure grip than smooth spherical knobs.
-
The “Screwless” Rose System: Utilizing a two-part assembly, a structural sub-rose is bolted through the door to provide maximum stability. The decorative ringed cover then “snaps” over the top, completely hiding the mounting screws. This creates a tamper-resistant, professional finish that looks “built-in” to the door leaf.
-
Internal Springing (Sprung Mechanism): Unlike many traditional “loose” knobs, these Concealed Fix Ringed Mortice Knob models typically feature a high-performance internal spring. This ensures the knob automatically returns to the horizontal position, reducing wear on the internal door latch.
-
Solid Sub-Chassis Construction: The internal mounting plate is designed to prevent “knob wobble.” By using M4 bolt-through fixings that “sandwich” the door, the knob remains perfectly rigid over years of high-frequency use.

Recommended Hardware Pairings
To maintain the premium feel of a Concealed Fix Ringed Mortice Knobb, it is essential to pair it with the correct internal and external accessories:
-
Architectural Mortice Latch: While these Concealed Fix Ringed Mortice Knob are often sprung, pairing them with a high-quality architectural latch (64mm or 76mm) ensures a silent, smooth “click” when the door closes.
-
76mm (3″) Backset: Because a ringed knob projects further than a flat lever, using a 76mm latch is highly recommended. This moves the knob further into the door, preventing “knuckle-clash” against the door frame.
-
Matching Concealed Escutcheons: For doors requiring a lock, use matching Concealed Fix Ringed Escutcheons to ensure the entire door maintains a consistent, screw-free aesthetic.
Installation Pro-Tip: The “Alignment & Snap”
A concealed fix installation is only as good as the initial alignment.
-
Centered Mounting: Insert the spindle through the latch first. Slide the sub-roses over the spindle to ensure they are perfectly centered.
-
Pilot Holes: Before driving the M4 bolts, drill small pilot holes. This ensures the sub-rose sits perfectly flush against the timber.
-
The Final Snap: Align the decorative ringed cover with the sub-rose. Apply firm, even pressure until you hear the audible click.
-
Grub Screw Check: Once the roses are snapped on, tighten the grub screw on the neck of the knob onto the flat side of the spindle. This removes any final “play” and makes the knob feel like a solid part of the door.
