Alpha A2313 48mm Uniline Platinum Crown & Drive

The Alpha A2313 Crown & Drive is a tubular motor accessory designed specifically for compatible installations using 48mm Uniline Platinum roller tube.

Alpha categorises the A2313 within its Crowns & Drives for 40mm Motors range, providing the mechanical interface required between a compatible Alpha 40mm tubular motor and the specified Uniline Platinum tube.

Unlike generic crown and drive components where the corresponding tube needs to be determined separately, Alpha clearly identifies the A2313 for 48mm Uniline Platinum tube.

Designed for 48mm Uniline Platinum Tube

Alpha’s specified application for the A2313 is straightforward:

Suits 48mm Uniline Platinum tube.

This makes the A2313 particularly useful when installing or replacing an Alpha tubular motor in an existing blind where the roller tube has already been identified as the Uniline Platinum 48mm system.

The 48mm measurement refers to the roller tube, while Alpha categorises the A2313 for its 40mm motor range.

For Alpha 40mm Motors

The A2313 forms part of Alpha’s range of crowns and drives for 40mm tubular motors.

Tubular motors are installed inside the roller tube, so the motor diameter and roller tube dimensions aren’t the same measurement.

In this case, the A2313 provides the interface between a compatible 40mm Alpha motor and the specified 48mm Uniline Platinum tube.

What Does the Crown & Drive Do?

A tubular motor needs to mechanically engage with the roller tube surrounding it.

The drive transfers rotational movement from the motor to the roller tube. As the motor operates, the correctly matched drive engages with the internal tube profile and causes the tube to rotate.

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

Together, these components allow the motor to operate correctly inside the compatible tube.

Replacing an Existing Blind Motor

The A2313 can be used where a compatible Alpha 40mm motor is being installed with a 48mm Uniline Platinum tube.

When replacing an existing motor, keep the original crown and drive until you’ve confirmed the replacement configuration.

Existing components may contain identifying markings or provide a useful physical reference when determining which replacement parts are required.

It’s also worth photographing the end of the roller tube before disposing of any existing motor components.

Confirm the Tube Profile

Although Alpha specifically identifies the A2313 for a 48mm Uniline Platinum tube, don’t assume that every roller tube measuring approximately 48mm uses the same crown and drive.

Roller tubes can have different internal profiles even where their nominal dimensions are similar.

The A2313 should therefore be selected where the existing tube has been identified as the compatible Uniline Platinum 48mm configuration.

If you’re uncertain about the tube fitted to your blind, use our Match Your Existing Blind Tube to the Correct Crown & Drive guide.

Matching an Existing Installation

For the best chance of correctly matching an existing blind, collect:

• Inside diameter of the roller tube
• Clear photograph looking directly into the tube
• Photograph of the existing crown
• Photograph of the existing drive
• Existing motor model or product code
• Any identifying markings on the existing components

This provides considerably more information than relying on tube diameter alone.

Important Compatibility Information

Alpha specifically identifies the A2313 as suitable for 48mm Uniline Platinum tube and categorises it within its Crown & Drive range for 40mm motors.

Don’t assume compatibility with another 48mm roller tube solely because its nominal diameter is similar. Confirm the tube system and internal profile before ordering.
