Anchor Point

You cannot use the LDS device without and anchor point.

If you do not have an adequate existing anchor point, you will be required to install one.

The type of anchor bolt you install will depend on the type of wall, floor on ceiling that you have.

Anchor points must be installed by a competent installer. Inadequate installation could result in fatal injuries to the user.

Ideally the anchor point should be installed in the ceiling above the window which one will exit from. If this cannot be done, the anchor point can be located on the floor, next to the window one will exit from.

It is recommended that you install your primary anchor point in the room/passage that you would most likely deploy from in the emergency situation. (See note in instruction manual on “Creating an escape plan”).

It is also recommended that you have a secondary anchor point somewhere else in the building (preferably on the roof or highest point on the building that is accessible). This will give you an alternate escape route should your primary route be unavailable for some reason (e.g. fire). One of the benefits of owning a LDS device, is that it is portable. You can carry it to any alternative escape point you choose to.

An anchor bolt (type FBN II M12) is included in the LDS kit. This anchor bolt is only suitable for installation into concrete. (It is not suitable for installation into brick, masonry or timber).

The specifications for this type of installation are as follows:


  1. For FBN II M12 bolt needs minimum concrete thickness of 120mm (4.7 inches).
  2. The loading for FBN II is based on C20/25 non-cracked concrete (20 MPa measured with cylinders with diameter 150mm and height of 300mm; and 25 MPa if measured with cube dimension of 150x150x150 mm3), so if the concrete grade is lower, the capacity will be reduced
  3. The anchor must be embedded a minimun 65mm deep into the concrete, minimum 70mm from the concrete edge, and if installed as a group of anchor, minimum 70mm from the other anchor (axial spacing), and if you are using torque wrench, you can set it to 50 Nm for tightening.
  4. Use a 12mm drill bit to make the hole on concrete.
  5. Drill depth into the concrete is 80 - 85 mm. (After the nut of the anchor is tightened, the anchor should be buried 77mm in the concrete.
