Alpha A2215 Uniglide 38mm Crown & Drive

The Alpha A2215 Uniglide 38mm Crown & Drive is designed to provide the mechanical connection between a compatible Alpha tubular motor and a Uniglide 38mm roller tube.

Unlike generic crown and drive components where the corresponding tube profile may need to be identified separately, Alpha specifically identifies the A2215 by its intended Uniglide 38mm application.

This makes the A2215 a straightforward option when replacing or installing a compatible Alpha motor into an existing Uniglide 38mm roller tube system.

Designed for Uniglide 38mm Tube

The defining feature of the Alpha A2215 is its compatibility with the specified Uniglide 38mm roller tube.

Tubular motors are installed inside the roller tube, so the motor requires correctly matched components to mechanically interface with the tube.

The A2215 crown and drive are designed around the profile of the compatible Uniglide 38mm tube.

Crown & Drive Function

The crown and drive perform different but complementary roles within a tubular motor installation.

The drive transfers the motor’s rotation to the roller tube. As the motor rotates, the drive causes the surrounding tube to rotate with it.

The crown forms part of the motor-to-tube interface and works with the corresponding tube profile.

Together, these components allow the tubular motor and compatible roller tube to operate as a complete system.

Replacing an Existing Motor

The Alpha A2215 can be useful when replacing the motor in an existing blind using a Uniglide 38mm tube.

If the roller tube itself remains suitable for use, matching the replacement motor with the correct crown and drive can allow the existing tube to remain in the blind.

Before ordering, however, it’s still worth checking the existing tube rather than relying solely on an approximate diameter measurement.

Check the Tube Profile

A roller tube measuring approximately 38mm doesn’t automatically mean it is a Uniglide 38mm tube.

The tube profile is important.

Look directly into the end of the existing tube and compare its shape with the appropriate tube profile.

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

The guide shows how to measure the tube and what photographs to provide so the existing tube can be matched to the appropriate crown and drive.

Existing Crown & Drive

If you’re removing an old motor, don’t throw away the existing crown and drive until you’ve confirmed the replacement components.

The original parts can provide useful information.

Check for product codes or other identifying marks and take clear photographs of both components.

Combined with the roller tube measurement and profile, this can make matching replacement components considerably easier.

Correct Compatibility Matters

Crowns and drives shouldn’t be selected purely according to an approximate tube diameter.

Different manufacturers and tube systems can use different internal profiles even where their nominal tube dimensions are similar.

The A2215 is specifically identified for the Uniglide 38mm configuration, so confirm that your existing tube matches that system before purchasing.

Important Compatibility Information

The Alpha A2215 is specifically identified for a Uniglide 38mm tube.

Don’t assume that every roller tube measuring approximately 38mm uses the same internal profile.

Confirm that your existing tube is the compatible Uniglide profile before ordering.
