Box lock sets – Ready-to-install complete solutions for gates and doors, available in square and round designs

A mortise lock set offers a professional and comprehensively designed solution for the secure, durable and visually appealing locking of gates, garden gates, industrial gates, sliding gates and external doors. Anyone building or refurbishing a gate or fence system often faces the challenge of precisely matching individual locks, lock cylinders, plates and handles. With a fully customisable box lock set, this hassle is completely eliminated: all components fit together perfectly, guaranteeing smooth operation and enabling quick, error-free installation.

1. Robust material quality and corrosion resistance

Locking systems used outdoors are constantly exposed to the elements, such as rain, moisture, UV radiation and temperature fluctuations. High-quality box lock sets therefore rely on an uncompromising combination of materials:

• Polished stainless steel: Visible components such as the lock case (depending on the model), the faceplate, the bolt and the latch are made of solid stainless steel and are precision-polished. This not only gives the system an elegant, modern look, but also offers excellent protection against rust.
• Galvanised lock mechanism: The internal gear mechanism and moving parts are hot-dip galvanised or electro-galvanised. This ensures a mechanism that remains smooth-running and low-friction over the long term, whilst protecting against premature wear.
• Aluminium fittings: The accompanying faceplate and handle sets are usually made from lightweight, highly durable aluminium, which harmonises perfectly with the stainless steel finish and is extremely weather-resistant.

2. The two lock case sizes in detail

To ensure optimal adaptation to different frame profiles and structural conditions, the box lock sets are available in two standard, professional sizes:

• Box lock 40 x 60 x 173 mm: The slim, compact standard version for narrower gate profiles, tubular frames and standard garden gates.
• Box lock 40 x 94.5 x 172 mm: The wider or deeper version for special installation situations and different spindle dimensions, which require greater stability for solid gate leaves.

3. Design variety: The choice between ‘Square’ and ‘Round’

As gate and fence systems must blend harmoniously into the overall architectural scheme, the sets are available in two distinctive design lines:

• Round design: Flowing lines, rounded short or long plates, and optional spherical knobs create a classic, timeless aesthetic that complements many traditional and modern fencing systems.
• Square design: Clean edges, geometrically precise plate shapes and straight handle or knob shapes emphasise a modern, technical and linear architectural style. They harmonise perfectly with rectangular metal profiles and modern gate designs.

4. Universal application: DIN left and DIN right

A key technical advantage of these box locks is their absolute flexibility during installation. Thanks to a rotatable latch, the locks are universally suitable for both DIN left and DIN right. Before installation, the fitter or DIY enthusiast need not worry about the exact opening direction – the latch can be adjusted to the specific installation situation in no time at all.

5. General contents of the complete sets

A typical complete box lock set contains all the components required for installation in the exact quantities:

• Lock case: In the selected dimensions (e.g. 40x60x173 mm or 40x94.5x172 mm), including a robust, galvanised internal lock as well as a faceplate, bolt and latch made from polished stainless steel.
• Lock cylinder: A matching profile cylinder (usually in the standard size of 60 mm or 30/30 mm) in a high-quality brass finish (often with a stainless steel look), including three keys.
• Fittings & plates: A choice of short or long cylinder plates (in round or square designs, made of aluminium).
• Handles & Latches: Depending on the set variant, either as a pair of double-sided door latches (straight design) or as a mixed set with a fixed, offset door knob (or ball knob) on the outside and a latch on the inside.
• Fixing: Includes a sturdy, galvanised handle spindle (e.g. 8x8x80 mm) and the necessary fasteners.

6. The benefits at a glance

• All-in-one solution: Perfectly matched components prevent incorrect purchases and fitting problems.
• Maximum durability: The combination of polished stainless steel and galvanised mechanisms drastically minimises maintenance requirements in outdoor environments.
• Flexible installation: Thanks to the swivelling latch, it can be used universally for both DIN left and DIN right.
• Wide selection: Available in two case sizes as well as in round and square designs to suit every taste and application.
