Oblique connector Model P angled joint with panel face for aluminium profiles — The Oblique Model P connector: an angled joint with a flat panel mounting surface. The panel face is on one side of the joint, aligned with the angle.

01What is the Oblique Connector Model P?

How is the Model P different from the Model C?

The Model C is a pure structural connector: it joins two profiles at an angle and nothing else. The Model P adds a flat panel mounting face on one side of the joint, aligned with the angle. So if two profiles meet at 60 degrees, the Model P gives you a 60-degree face to bolt a panel onto. The Model C gives you only the structural joint.

Why would you need a panel at the angle?

On a clad frame — an enclosure, a machine guard, a display unit — the panels are the visible surface and they follow the frame geometry. If the frame has an angled corner, the panel at that corner has to sit at the same angle. Without the Model P, you would have to fabricate a custom bracket to hold the panel at the right angle, or mitre-cut the panel itself.

Is the panel face structural or cosmetic?

Both. The panel face has tapped holes or a short T-slot that takes panel fixings. When the panel is bolted on, it becomes part of the structure: the panel carries shear that the tie rod alone cannot, and the joint becomes stiffer. This is why the Model P is recommended for angles outside the 45 to 120 degree range where the Model C alone is weaker.

Oblique connector Model P with panel face — The Model P has a panel mounting surface on one side of the angled joint. The face is at the same angle as the joint, so a panel can be bolted directly to the connector without a separate bracket.

02How it works

The connector has four parts: the central housing (zinc alloy) with the panel face, the tie rod (steel) that pulls the profiles together, the threaded insert in the second profile, and the panel fixing points on the face.

Part	Material	Function
Central housing with panel face	Zinc alloy (Zamak)	locates the corner, sets the angle, provides the panel surface
Tie rod	Steel, zinc plated	locks the angle and pulls profiles together
Threaded insert	Steel, zinc plated	receives the tie rod in the second profile
Panel fixing holes	Tapped M4 / M5 / M6 by series	bolt the panel to the face

03The panel face: what it adds beyond the Model C

The panel face is the only difference between the Model P and the Model C, but it changes the application completely. Three things the panel face does:

What the panel face does	Why it matters	How to use it
Provides a flat mounting surface at the joint angle	no need to fabricate a custom bracket	bolt the panel directly to the tapped holes on the face
Adds stiffness to the joint	the panel carries shear that the tie rod alone cannot	use for angles outside 45-120 degrees where the Model C is weaker
Gives a finished appearance	the panel covers the connector housing and the profile ends	use on visible frames where the connector would otherwise be exposed

04Panel fixing: how to mount the panel

The panel face has a row of tapped holes sized to the series: M4 for 20 series, M5 for 30 series, M6 for 40 series and M8 for 45 series. The holes are on a pitch that matches the profile slot pitch, so a panel can be mounted with the same bolts and spacing used on the profile faces.

Series	Panel hole thread	Hole pitch	Panel thickness
20 series	M4	20 mm	1.5 to 3 mm typical
30 series	M5	30 mm	2 to 4 mm typical
40 series	M6	40 mm	2 to 5 mm typical
45 series	M8	45 mm	3 to 6 mm typical

The panel material can be aluminium sheet, acrylic, polycarbonate, composite panel or steel sheet. For a structural panel (one that adds stiffness to the joint), use aluminium at 2 mm minimum or steel at 1.5 mm minimum. For a cosmetic panel, acrylic or polycarbonate at 3 mm is typical.

05Model P vs Model C: when the panel face is worth it

Choose Model P (with panel face)

You need to mount a panel at the joint angle
The angle is outside 45 to 120 degrees and needs the panel for stiffness
The connector will be visible and needs a finished cover
You are building a clad enclosure with panels at every corner
The panel is structural and carries shear

Choose Model C (no panel face)

The joint is purely structural — no panel at the angle
The angle is within 45 to 120 degrees where the C is adequate
Cost matters — the C is cheaper than the P
Panels are mounted elsewhere, not at the joint
You want simpler assembly (fewer parts)

06Stiffness gain from the panel

When a structural panel is bolted to the Model P face, the joint gains shear stiffness that the tie rod alone cannot provide. The panel acts as a gusset: it carries the shear force that the housing would otherwise carry alone. The effect is most pronounced at extreme angles.

Angle	Model C alone	Model P with structural panel	Improvement
30 degrees	4 kN shear	8 kN shear	+100 per cent
45 degrees	5.6 kN	9 kN	+61 per cent
90 degrees	0 kN shear	0 kN	no gain (balanced)
120 degrees	4 kN	8 kN	+100 per cent
150 degrees	7 kN	10 kN	+43 per cent

The panel stiffness values assume a 2 mm aluminium panel bolted to every hole on the panel face with the series-standard bolts. Thinner panels or fewer bolts give proportionally less improvement. The values are for joint design only.

07Applications: where the Model P earns its place

Clad enclosures with angled corners: the panel follows the frame angle, bolted directly to the Model P face.
Machine guards with angled access panels: a guard panel at 60 or 120 degrees, bolted to the connector face.
Display units and exhibition frames: angled corners with a visible panel that covers the connector.
Roof and canopy structures: the panel (roof sheet) bolts to the connector face at the ridge or eaves angle.
Structural joints at extreme angles (below 45 or above 120): the panel adds the stiffness the tie rod alone cannot provide.

08Failure modes to design out

What goes wrong	Why it happens	Design it out by
Panel does not sit flush on the face	the panel is warped or the face has a burr	specify a flat panel; deburr the face; use a gasket if needed
Panel bolts strip the tapped holes	over-tightened or the panel is too thick for the bolt	use the correct bolt length; torque to the data sheet value
Angle drifts with the panel mounted	the panel was mounted before the tie rod was torqued	torque the tie rod first, then mount the panel
Panel cracks at the bolt holes	the panel material is too brittle (acrylic) or the holes are too tight	use oversize holes in acrylic; use polycarbonate for impact
Joint is still weak at 30 degrees even with panel	the panel is too thin or not bolted to every hole	use a 2 mm minimum aluminium panel; bolt to every hole on the face

09What to check before you order

Procurement checklist for the Oblique Model P

Confirm the series: 20, 30, 40 or 45. The connector and panel hole size are sized to the series.
Confirm the angle or range of angles the joint needs.
Confirm the panel material and thickness: aluminium 2 mm minimum for structural, acrylic/polycarbonate 3 mm for cosmetic.
Confirm the panel bolt pattern: match the hole pitch on the face.
If the angle is within 45 to 120 degrees, consider the Model C instead — it is cheaper and the panel face is not needed for stiffness.
Confirm the finish: zinc plated standard, black or nickel for aesthetic.

10Questions buyers ask

What is the difference between Model P and Model C oblique?

The Model P has a flat panel mounting face on one side of the joint, aligned with the angle. The Model C does not — it is purely structural. The P is used when a panel needs to sit at the joint angle.

Can I use the Model P without a panel?

Yes, but it is more expensive than the Model C for the same structural job. If no panel is needed, use the Model C.

What panel materials work with the Model P?

Aluminium sheet (2 mm minimum for structural), acrylic or polycarbonate (3 mm for cosmetic), steel sheet (1.5 mm minimum), composite panel. The panel bolts to the tapped holes on the face.

Does the panel add strength to the joint?

Yes. A structural panel (2 mm aluminium, bolted to every hole) acts as a gusset and can double the shear capacity at extreme angles (30 or 150 degrees).

What is the angle range?

Typically 30 to 150 degrees. At 90 it matches the miter Model C; at 45 the miter Model P.

What is the minimum order quantity?

Stocked item; minimum 50 pieces per series. Production runs quoted per piece.
