FIXING INSTRUCTIONS

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

We recommend regular cleaning using a cloth moistened with soapy water. Our products are carefully chosen for their reputation of long term quality, and under normal use will provide many years of service. However please note that after a period of time the lacquer coating applied to brass products can suffer a possible 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 has begun to break down 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. Florentine Bronze These products should be treated in the same way as brass products. As the bronze is an applied finish it will weather over time enhancing the antique effect.

DOOR KNOBS

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.

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.

Escutcheon

A key hole cover commonly used with Door Knobs when a door Lock is required. Many different styles are available. Note - Door Knobs with a large diameter Rose (eg. 70mm) may not fit with all Escutcheons.

Face Fix Rose

The Rose has rebated holes (usually 3/4) to allow screws to be face-fixed through the Rose and into the door. The screw heads can still be seen once fixed. Mortice Knob This Knob is designed to be fitted to a Mortice Latch / Lock. They are supplied as a pair of identical Knobs on a Rose. They may be either sprung or unsprung (see below) depending on the design of the Rose.

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.

Rim Knob

This Knob is designed to be fitted to a traditional style Rim Latch / Lock (A self contained latch / lock concealed in it’s own case fixed onto the inside face of a door). They are supplied as a pair with one knob on a Rose and the other free to be fitted to the Rim Latch / Lock.

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 / Plate to return the knob after it has been released - the knob needs to return in order to secure the latch.

Turn & Release

A Thumb-turn and Emergency Release are commonly used with Door Knobs to operate a Bathroom Lock, many different styles are available. Note - Door Knobs with a large diameter Rose (eg. 70mm) may not fit with all Thumb-turns.
