FIXING INSTRUCTIONS
Our products are supplied with fixing instructions as required.
Pilot Holes
We recommend that you always drill a suitable sized pilot hole hole for all screws. A pilot hole drilled correctly should allow the screw to be turned with minimal effort whilst still feeling a small amount of reassuring biting pressure. To aid the screw you might wish to rub the screw with candle wax before fitting.
CARE INSTRUCTIONS
Brass Products
Many brass products are supplied with a lacquer coating, which helps to maintain the high polished finish without the need for regular metal polishing. We do recommend regular cleaning using a soft cloth moistened with soapy water and immediately dried. This will keep any residue from forming on the lacquer and causing it to break down. Our lacquered brass products are carefully chosen for their reputation of long term quality, and under normal use will provide many years of service.
Please note that after a period of time the lacquer coating applied to brass products can sometimes begin to breakdown, usually on external fittings. The life of the lacquer is beyond the manufacturer’s control and therefore cannot be guaranteed. If the lacquer coating does begin to break down, you can remove the brass fittings and treat with an acetone thinner to completely remove all of the lacquer (e.g. Nitramors applied according to the manufacturer’s instructions). Ensure that the fitting is completely dry and then apply a metal polish such as Brasso. This can be reapplied whenever it is required or the fitting can be re-lacquered.
CUPBOARD HANDLES & KNOBS

There is a huge variety of styles and finishes available.
Cupboard Knobs

Please contact us directly if you have any questions.

All these handles are supplied with Euro Profile key hole cut outs, and are unsprung - allowing the Lever to be pushed up in order to engage the locks. Various Lock Centres are available to suit different lock systems.
DOOR HANDLES ON ROSE
Concealed Fix Rose
The Rose has no visible holes or fixing marks as the Rose is in 2 parts with a separate cover to conceal the fixings. The Rose Cover may be a simple push on cover, while more expensive handles will use a machined screw-on cover.
Face Fix Rose
The Rose is a more traditional design and has counersunk holes (usually 3/4) to allow screws to be face-fixed through the Rose and into the door. You can still see the screw heads once fixed and so the screws are usually decorative round head slotted screws.
Escutcheon
A key hole cover commonly used with Levers On Rose when a door Lock is required. Choose from Euro, Oval or Standard profile depending on which type of lock you are using it with. Many different styles are available to match the chosen handles..
Turn & Release
A Thumb-turn and Emergency Release which are commonly used with Levers On Rose to operate a Bathroom Lock. Usually fitted directly under the door handle, many different styles are available to match the chosen handles.
DOOR KNOBS
Mortice Knob
These knobs are supplied as a pair and are designed to be fitted directly to the door. Each knob has a matching rose that sits onto the face of the door. The Latch / Lock is morticed inside the door, meaning only the door knobs are visible.
Rim Knob
These knobs are supplied as a pair and are designed to be fitted to a traditional style Rim Latch / Lock. One knob has a matching rose that sits onto the face of the door, the other knob has no rose as it fits directly to the self contained latch / lock concealed in it’s own case which is surface mounted onto the inside face of the door.
Sprung vs Unsprung
Door Knobs are supplied either Sprung or Unsprung. This will be specified for each product and indicates whether a spring mechanism is fitted behind the Rose to return the knob after it has been released - the knob needs to return in order to secure the latch.
Backset Size
It is important when fitting Door Knobs to ensure you use a Latch / Lock with a longer Backset size. The Backset measurement determines how far from the edge of the door your Door Knob will be positioned. When turning the Door Knob if it is fitted too close to the edge of the door you will find your finger knuckles catching on the door frame! We recommend using a Latch / Lock with a minimum Backset of 57mm.
Centre Door Knobs
This knob is designed to be fitted as an external Knob on a front door. It is secured with an M6 Bolt-Through Fix and cannot be used with a Latch / Lock. The bolts are supplied with decorative nut fixings which will be visible on the inside of the door.
Other Considerations
A Door Knob may be awkward to operate for those with mobility issues such as arthritis or for young children. A Lever Door Handle is much easier to operate as it does not require the same action of grip that is needed on a Door Knob.
If you wish to use a Door Knob with a Lock please note that Door Knobs with a large Rose diameter (eg. 70mm) will not fit with all Escutcheons / Thumb-turns as the lock Centres of 57.5mm limit the placement of the Knob and Escutcheon. Please call us if you are unsure.
Concealed Fix Rose
The Rose has no visible holes or fixing marks as a separate fixing plate is used underneath the Rose. The Rose has an integral threaded socket underneath which allows it to be securely fitted to the fixing plate. Cupboard Knob This Knob is designed to be fitted to a cupboard or cabinet door. It is secured with an M4 Bolt-Through Fix and cannot be used with a Latch / Lock. Many cupboard knobs are designed to match the larger Mortice Knobs.
Face Fix Rose
The Rose has countersunk holes (usually 3/4) to allow screws to be face-fixed through the Rose and into the door. You can still see the screw heads once fixed and so the screws are usually decorative round head slotted screws
Escutcheon

Overall Size - vertical & horizontal.
Aperture Size - vertical & horizontal.
Fixing Centres - distance between the two fixing bolts.
