The Object

Crystalset in a brass frame

The Hvalvik Knob pairs a real crystal catch with a brass or chrome frame — the crystal catches the light from whichever angle the room offers it, and no two pieces are exactly alike. Available as a knob or a 15 cm pull bar, in brass, chrome, pink, green, yellow, or purple crystal combinations. Fits cupboards, cabinets, drawers, and wardrobes with standard fixings; lightweight at 113 g for the knob, 226 g for the pull bar.
Why you'll love it
  • Natural crystal — each piece genuinely unique, catches light differently
  • Brass or chrome frame — weighty, warm, built to last
  • Available as knob or pull bar — one system, two formats
  • Five crystal colour options: brass, chrome, pink, green, yellow, purple
  • Fits cupboards, drawers, cabinets, and wardrobes with standard fixings
Details

No wiring here — just careful measuring, drilling, and mounting. Mortice locks take a bit more patience than a simple knob.

Before you begin

  • Mounting — surface installation on doors, drawers, or cabinetry; check your product's dimensions for placement and drilling points

What you'll need

  • Screwdriver (Phillips and flathead), drill and drill bits, Allen key
  • Tape measure, pencil, level
  • Chisel (for mortice lock installation)
  • Screws and anchors, safety goggles

Step by step

  1. Cabinet hardware — mark drilling points — use a tape measure and pencil; a template helps for uniformity across multiple pieces.
  2. Cabinet hardware — drill holes — use a bit matched to the screw diameter, keeping the drill straight.
  3. Cabinet hardware — mount — insert screws from inside the cabinet or drawer, secure the hardware on the front face, and tighten without overtightening.
  4. Cabinet hardware — align and inspect — confirm straightness and spacing before fully securing.
  5. Thumb lock or dummy handle — confirm orientation — determine left- or right-hand door swing and adjust as needed.
  6. Thumb lock or dummy handle — mark installation height — typically 36–38 inches from the floor to the handle center; align the mounting plate.
  7. Thumb lock or dummy handle — drill and attach — drill pilot holes and secure the backplate and handle with the included screws. Dummy handles install directly, no latch mechanism.
  8. Thumb lock only — install the strike plate — mark the latch location on the door frame, chisel a recess if needed, and screw the strike plate in.
  9. Mortice lock — cut the mortice pocket — use a chisel and drill to create a cavity in the door edge, following the provided measurements.
  10. Mortice lock — insert the lock body — fit it into the cavity and attach through the faceplate with screws.
  11. Mortice lock — install the handle — align the spindle through the lock, attach handles on both sides, and tighten with a screwdriver or Allen key.
  12. Mortice lock — install the cylinder (if applicable) — insert the key cylinder and secure with the cylinder screw from the door edge.
  13. Mortice lock — mount the strike plate — align with the latch mechanism and secure to the door frame.

Good to know

  • Double-check measurements before drilling.
  • Use a level for consistent alignment across multiple units.
  • If you're unfamiliar with mortice installation, consult a locksmith or professional.
  • Make sure all moving parts operate smoothly before final tightening.
  • Dummy handles are decorative or pull-only — they don't engage latches or locks.

On the detail

Crystallit from every angle in the room

Natural crystal behaves differently from glass — the internal facets catch light from multiple directions and scatter it back into the room at a slightly different angle than you'd expect. The Hvalvik uses this quality deliberately: the brass setting holds the crystal steady, and the crystal does the rest. Open a drawer fifty times a day and you'll notice the light in it change.

Innovative engineering · intelligent design
Real crystal

Genuine natural crystal — never identical, catches and scatters light with a depth no glass copy matches.

Two formats

Choose a knob (5–7.5 cm) or a 15 cm centre-to-centre pull bar — same crystal, same brass setting.

Six finishes

Brass, chrome, pink, green, yellow, or purple crystal — wide enough to suit any cabinet colour or room palette.

Frequently asked

Yes — the brass frame and natural crystal combination sits naturally in both period and contemporary settings. The classic proportions work well on older cabinetry and period-appropriate joinery.

Natural crystal set in a solid brass or chrome-plated brass frame. The crystal is genuine — not glass or resin — so each piece carries its own internal variation.

Standard single-screw installation for the knob; two-screw for the pull bar. Hardware is included. Most installations take a few minutes with a screwdriver — no specialist tools needed.

Yes — the brass frame is solid and built for daily use. Natural crystal is harder than glass and resists chipping under normal cabinet use. Nava covers these with a 1-year warranty, extendable to 2 or 3 years.

Yes — screws and fixings are included in the box. No additional hardware to source before installation.

Yes — they fit standard cabinet and drawer boards in wood, MDF, glass, and metal, wherever a standard bore hole can be drilled. Cupboards, wardrobes, kitchen cabinets, and bathroom vanities all suit them.

Nava Decor accepts returns within 14 days of delivery for items in original, unused condition. Contact our team to start the process — we respond promptly.

Wipe with a soft damp cloth. Avoid abrasive cleaners on the crystal or brass frame — they can dull the finish over time. A dry buff with a microfibre cloth restores shine quickly.

Yes — all Nava Decor hardware carries a 1-year warranty as standard, extendable to 2 or 3 years on request. Reach out before or after purchase to arrange.
