The drilling is the easy part, and it is not the part that matters. Mounting ends in a bench test that measures whether the binding releases near its setting, and that equipment is what a workshop has and a home does not.
What mounting involves
A paper or metal jig positions the holes for that binding on that ski, at the mounting point the maker marks. The holes are drilled to a specified depth and diameter, glued, and the binding screwed down. The heel piece is then adjusted to the boot sole length, the toe height set for the sole standard the boot carries, and the release value set from the published procedure.
Then the assembly goes on a machine that applies a twisting and a forward load and records where it lets go. That result is compared with the setting, and the binding is adjusted until they agree.
Why the test is the point
A binding that has never been tested has a number on a dial and no evidence behind it. Friction in the toe, a dirty boot sole, a heel adjusted to the wrong sole length: every one of those changes the release and none of them is visible.
This site prints a binding’s declared range and refuses to print a setting, for the same reason: the setting without the test is half a procedure.
The other things a shop catches
That the boot’s sole standard is one this binding accepts — alpine, walk sole, touring — and that the toe is set for it.
That the brake clears the ski.
That the old holes, if the ski has been mounted before, do not compromise the new pattern.
What you can reasonably do at home
Check that the boot is centred on the marked line and that the brakes retract cleanly. Note the sole length on your boot heel so you can give it to anyone who works on the skis. Keep the binding’s own instructions, which name the tolerances.
How this site prints it
Binding pages print the declared range, the brake width, the sole standards accepted, the stated weight and the spare brake widths the maker lists. They point at the workshop for everything past that, and they do not describe any binding as safe.
Where this page and a maker’s own documentation part company, the documentation is right. Every length, waist width, radius, flex index, last width, DIN range, brake width, filter category, temperature band and mass on this page comes from the maker’s own published figures, with the unit as printed and the source named. None of it is measured here, and no figure is converted into another convention, because a converted number is a different number. And the two things this page refuses to merge: a DIN range is a property of the binding; a release setting is a number a workshop calculates for one skier. The range comes from the maker and is printed here as published. The setting depends on height, weight, age, ability and boot sole length, it is set and tested on a bench, and it is not something this page will ever suggest.
The questions asked most often
What does a shop need to know?
Your height, your weight, your age, your boot sole length and your self-declared skier type — and the boots themselves, because the binding is adjusted to them and tested with them in.
Can a binding be moved to another ski?
Usually yes, if the brake width suits the new ski and the old holes do not fall where the new ones need to go. Both are questions for the shop that will do it.
