Q: What is the advantage of the Jig when my installers just use an offcut to mark their holes?
A: The jig is guaranteed to save time and be safer. The offcuts have caused serious injuries as they can catch up the drill. Also saves having to throw out aluminium when the holes are drilled incorrectly.

Q: Do I need a different Drilling Jig for each system?
A: Due to the hole centres for the various systems being different we have designed the minimal number of jigs possible. For example the Platinium & Definium 90 centre glaze share the same jig.

Q: How long to the Drilling Jigs last?
A: Like any tool it depends on the care of the user. With constant everyday use, we would expect that after a couple of months that the holes would be effected by continuous drilling.

Q: Can I drill for for Sill or Standard Frame for the horizontals?
A: Yes it clearly marked on the Drilling Jig as to which hole is which.

Q: Can I Drill a middle mullion at particular heights?
A: Yes the plate of the Jig has two small pins at the top, if you place the jig on the extrusion with the pins facing towards you it can then slide up and down within the glazing pocket and the markings on the side of the plate allow you to align at exactly the right locations.
