HEOSafe Door Frame Lock 1750 is a high quality external lock with mounting plate with is fitted to the motorhome body adjacent to the frame of habitation doors, garage doors and service doors. In the locked position it is rotated on the base plate so that it overlaps the door which then cannot be opened.

The action is similar to the Heosafe universal twist locks 1760 (which are for van sliding doors and rear doors) but it has an additional right-angled extension to the mounting plate so that it wraps around the internal edge of the frame and allows it to be secured there as well as to the outer body surface.

This lock can be used on any opening side irrespective of whether it is on the left or right or opening downwards or upwards.

Available in three colours: white (W), grey-silver (G) or black (S). This is the purchase page for the WHITE version.

This lock is supplied with three keys which are unique to each lock (or to each set of locks when they are purchased as a set - see the next paragraph.

It is also possible to order the lock as part of the Heosafe single-key system which offers sets of up to 5 locks which can all be operated with the same set of keys: one key is usable for all locks in the purchased set. Please note that the single-key sets must be ordered separately as a set; if you can't locate the combination you want on our website please contact us. Some combinations are only available to order and may take longer to obtain.

The HeoSafe 1750 Frame Lock lock is simple to install and easy and safe to use. Its clever 'twistlock' operation allows it to be set to either allow or prevent opening of the door simply by rotating it 180 degrees. It can only be rotated if it is first unlocked using the key which means that occupants can't be locked inside by someone outside who doesn't have the key. Nor can the door be unlocked without the key when the vehicle is not occupied.


In this installation position (body at 90 degrees) the bolts which fix the main body to the mounting plate underneath are accessible and the key cannot be withdrawn. In use the lock is always horizontal (locked or unlocked) and the bolts are covered and the key cannot be withdraw.


The lock body is rotated, in which position it extends beyuond the door frame and over the door which then cannot be opened.

In its normal horizontal positions the lock's main body covers the screws which fix the base plate to the vehicle body; when the main locking body is rotated through only 90 degrees the fixing holes are exposed so that the unit is easily fitted. The key cannot be removed while it is in intermediate position.

An example of the attention to detail in the design of these locks is that the keys can be inserted either way into the keyhole, so there is no fumbling and irritation through trying to insert it the wrong way. And the same lock can be installed on either the left or right side of the vehicle.

The lock bodies are made of aluminium and are anodised before powder coating to protect against corrosion (they have a three year corrosion warranty).

Instructions for use

Unlock the lock, turn the main body to the desired horizontal position (door opening allowed or prevented) and pull out the key.

Please only use this lock from the outside. We strongly advise that you should not have it locked when you are inside your mobile home: emergency escape ways and doors should remain accessible.

Always keep a key at hand!

The key can be removed only when the lock is in a normal operating position. Without the key the lock can't be operated. As a consequence there is no danger that someone outside without the key can operate the lock.

  • Assembly instructions
  • (See also the photos below which illustrate the main steps involved)
  • Disassemble the lock from the mounting plate: open the lock with the key, turn the lock part 90 degree (assembly position). Remove the 4 screws. In the assembly position the key cannot be removed.
  • Assembly of the mounting plate, which you disassembled from the lock system, at the door frame. A gap of at least 5 mm between door/hatch and frame is needed.
  • Mark all required drill holes on the frame with a pencil or hold the plate on the frame. Take care that the inner surface of the door, hatch or garage door is not damaged. Choose the most suitable four holes taking into account any furniture on the inside of the motorhome.
  • Drill the holes using following drill bits
  • For the fixing into the inside edge of the door frame pre-drill the two holes with a drill bit of diameter 2mm.
  • For the fixing into the front face of the door frame pre-drill the four holes with a drill bit of diameter 5.5mm.
  • After pre-drilling remove the plate and clean away the drilling debris. Shorten the screws for the frame mounting at the correct length with a metal saw and tighten the plate on the frame and at the ridge of the frame.
  • Screw the covering part (the lock system) back on the mounting plate.
  • The HEOSafe Door Frame Lock is now functioning.
