Alpha A2310 Acmeda 43mm & 49mm Crown & Drive

The Alpha A2310 Crown & Drive is one of the key crown and drive combinations in Alpha’s 40mm tubular motor accessory range.

Alpha specifies the A2310 for several commonly used roller tube configurations:

• Acmeda 43mm tubing
• Acmeda 49mm Heavy Duty tubing
• Blindware 45mm tubing

Importantly, Alpha also states that the A2310 comes standard with all 40mm motors.

This makes it particularly relevant both when purchasing a new Alpha 40mm motor and when identifying the standard crown and drive supplied with an existing Alpha installation.

Standard with Alpha 40mm Motors

A major distinction between the A2310 and many other crown and drive options is that Alpha identifies it as the standard crown and drive supplied with all 40mm motors.

That means customers purchasing a compatible Alpha 40mm motor should take this into account before separately purchasing an A2310.

A separate A2310 may instead be required as a replacement component or where an additional crown and drive is needed.

If your roller tube doesn’t match one of the A2310’s specified tube systems, a different crown and drive may be required even though the motor itself is a 40mm Alpha model.

Acmeda 43mm Compatibility

Alpha specifies that the A2310 suits Acmeda 43mm tubing.

When used with the correct Alpha 40mm motor and compatible Acmeda tube, the crown and drive provide the mechanical interface between the tubular motor and roller tube.

Acmeda 49mm Heavy Duty Compatibility

The A2310 is also designed for Acmeda 49mm Heavy Duty tubing.

The “Heavy Duty” designation is specifically included in Alpha’s product description, so customers should confirm that their existing 49mm Acmeda tube is the corresponding Heavy Duty configuration rather than relying solely on its approximate diameter.

Blindware 45mm Compatibility

Alpha additionally lists Blindware 45mm tubing as compatible with the A2310.

This gives the same crown and drive combination applications across multiple specified roller tube systems while retaining compatibility with Alpha’s 40mm motor range.

What the Crown & Drive Do

A tubular motor is installed inside the roller tube rather than externally driving the blind.

The drive transfers the rotational movement of the motor to the surrounding roller tube. As the motor rotates, the correctly matched drive engages with the tube and causes it to turn.

The crown forms another part of the interface between the motor and roller tube.

Correct crown and drive selection is therefore necessary to mechanically match the motor to the particular roller tube being used.

Motor Size vs Tube Size

The different measurements associated with this product can initially appear confusing.

The A2310 is categorised by Alpha as a crown and drive for 40mm motors.

The 43mm, 45mm and 49mm measurements refer to the compatible roller tubing, not different motor sizes.

This distinction matters when selecting components for a replacement or retrofit motor installation.

Replacing an Existing Motor

If you’re replacing an existing Alpha 40mm motor and the installation uses the standard A2310 crown and drive, check whether the components are still serviceable and whether replacements are actually required.

If you’re uncertain what is currently installed, retain the existing crown and drive when removing the motor.

Look for identifying marks and photograph both components as well as the end profile of the roller tube.

Match the Tube, Not Just the Diameter

Although Alpha provides several confirmed applications for the A2310, don’t assume that every tube measuring approximately 43mm, 45mm or 49mm will fit.

The specific tube system and internal profile matter.

For the A2310, Alpha specifically identifies Acmeda 43mm, Acmeda 49mm Heavy Duty and Blindware 45mm.

If you can’t identify your existing tube, use our Match Your Existing Blind Tube to the Correct Crown & Drive guide before ordering.

Important Ordering Information

Alpha states that the A2310 comes standard with all 40mm motors.

If you’re buying a new Alpha 40mm motor, check what is already included before purchasing an additional A2310.

If your existing tube isn’t Acmeda 43mm, Acmeda 49mm Heavy Duty or Blindware 45mm, don’t assume the standard A2310 is the correct crown and drive simply because you’re using a 40mm Alpha motor.
