STEP 1 – check items

When check-measuring for an insect OXXO door, don’t forget to note down the compulsory items and any accessories you will need to complete the job. 

These can include interlocks, bug strips, H receivers and sometimes top and bottom tracks.

For this job, we are installing 2 F interlocks, a H receiver two 25mm bug strips, one for each sliding door.

STEP 2 – Measure the width

In this example, measuring the width of both doors from interlock to interlock gives us 2022mm. Deduct 4mm to compensate for lock striker plate and H receiver. Then dive by 2 and deduct 1mm to a manufacture size of 1008mm.

STEP 3 – Measure the height

Measure the height from the top pip track to the bottom pip track. Measure the left, middle & right sides. This door is reasonably straight with 2400 mm as the opening size. Deducting 14mm for top and bottom wheels gives a manufactured size of 2386 mm.

STEP 4 – Measure the lock height

Measure from the bottom channel to the top of the glass door handle. Add around 40 mm. The lock height will be 1150mm.

STEP 5 – Measure midrail position

If the door height is taller than 500mm, a mid-rail is needed.  Measure from the bottom channel to the centre of glass decals. In this case, 1030 mm. Deduct 10 mm to compensate for the bottom wheels.

STEP 8 – measure H receiver

Once the doors are square, measure the H receiver. In this case, 2380mm. Deduct 4mm for the cut size. Note that this is a custom cut, because the H Receiver is close to the bottom sill. Then fix your H receiver with pan head screws.
