Description
Mitre-Fastening Sets are suitable for connecting two aluminum extrusion profiles at an angle. They are used primarily when constructing frame elements and panel edging. The profile grooves facing each other inside the frame remain unobstructed so they can be used for holding panel elements.

The position of the clamping pins at right angles to the cut profile edge generates particularly high clamping forces on the fastening elements. The clamping screws are accessed from the side of the profile frame.

Mitre-Butt-Fastening Set 8

Two mitred profiles (each with an identical angle γ between 30° and 90°) are connected together. This gives a possible angle between the profiles of  between 60° and 180°.

Note: Despite the optimized design, the flow of forces across the inclined contact faces of the profiles is such that only part of the pretension of the screw connection is utilized. Mitre connections therefore have a lower load bearing capacity than other, right-angled profile connections (Standard-Fastening,
Universal-Fastening or Automatic-Fastening Set).
Mitre-Fastening Sets should therefore not be used for constructing basic frames and safety-related parts that are subject to high loads.

Using Mitre-Butt-Fastening Set 8:
1. Mitre both profiles at an angle γ.
2. Drill counterbores of diameter 14.2 mm for the fastener sleeve in the side of the profile (use of a drilling jig is recommended).
3. Drill a 9 mm dia. hole into the mitred face of both profiles (use of a drilling jig is recommended). The minimum drilling depth is 12 mm.
4. Insert the threaded fastener sleeve into the counter- bore of one of the profiles and screw in the clamping pin until the mark around the perimeter is level with the cut profile edge.
5. Secure the clamping pin in the threaded fastener sleeve using grub screw DIN 915 (M = 15 Nm).
6. Insert the fastener sleeve with bore into the second profile and fit the assemblies together.
7. Drive the special grub screw M10 into the fastener sleeve and tighten the profile connection (M = 15 Nm).
8. Fit the Caps onto the fastener sleeves.
