Aluminum Post Cover For Channels

0 (0) Reviews

A multipurpose snap-in aluminum channel cover for Alumission posts and gate frames. Use it to close unused channels, conceal channel screws, or cut custom spacers between slats.

Price range: $13.89 through $21.66

The Aluminum Post Cover For Channels is a multipurpose finishing profile for Alumission posts and gate frames. It works with the Aluminum Post 2 Channels, Aluminum Post 3 Channel, Aluminum Side Post, and Aluminum Gate Frame to create a clean, continuous powder-coated surface.

Its main purpose is to close a post or frame channel that is not being used for slats. It can also conceal screws installed inside a compatible channel, reducing visible fasteners after the slats are secured.

The full-length extrusion can be cut into shorter pieces and used as custom spacers between aluminum slats. Specific pre-cut spacer sizes are also available separately when a project needs faster installation and repeatable standard gaps.

System Compatibility

One Cover for Alumission Posts and Gate Frames

Use the same cover profile across compatible Alumission fence and gate components for a consistent finished appearance.

Post 2 Channels

Close an unused compatible channel or cover fastening points inside the channel.

Post 3 Channel

Finish the third channel when an inline or corner fence layout uses only two channels for slats.

Side Post

Close and finish the compatible channel area where the installation requires a continuous powder-coated face.

Gate Frame

Conceal screws or finish a compatible frame channel that is not being used for slats.

Clean Finished Channels

Close Unused Openings and Conceal Screws

The snap-in profile creates a clean finishing layer after slats and fasteners have been installed.

Unused Slat Channels

Close a post or frame channel that is not carrying slats so the exposed side looks complete.

Concealed Fasteners

Cover compatible screws installed inside the channel to reduce visible hardware.

Color-Matched Finish

Select a powder-coated color that matches the post, frame, and slats.

Planned Service Access

Choose cover lengths and joint locations so the assembly can be accessed later if service is required.

Custom Slat Spacing

Cut the Cover into the Spacer Size You Need

Cross-cut the extrusion into short pieces for controlling gaps between Alumission slats.

Custom Gap Sizes

Cut pieces to the exact spacer width required by the fence or gate pattern.

Consistent Installation

Use pieces cut to the same length to repeat the planned gap across the complete panel.

Pre-Cut Options

Specific ready-sized Alumission spacers are sold separately for standard repeatable gaps.

Cut and Deburr

Use suitable aluminum-cutting equipment, verify the measurement, and deburr every cut edge.

Included: One Aluminum Post Cover For Channels in the selected length and powder-coated finish.

Sold separately: Posts, gate frames, slats, pre-cut spacers, screws, caps, bases, reinforcement, and installation hardware.

Questions & Answers

Aluminum Post Cover For Channels Questions & Answers

Answers about compatible Alumission posts and frames, unused-channel finishing, concealed screws, custom-cut slat spacers, installation, sizes, finishes, ordering, and maintenance.

Compatibility & Main Uses

What is the Aluminum Post Cover For Channels used for?

It is mainly used to close a post or frame channel that is not receiving slats and to conceal compatible screws installed inside the channel.

Which Alumission profiles accept this cover?

It is designed for compatible channels on the Aluminum Post 2 Channels, Aluminum Post 3 Channel, Aluminum Side Post, and Aluminum Gate Frame.

Can it be used on the Aluminum Post 2 Channels?

Yes. It can close an unused compatible channel or cover screws inside the channel.

Can it be used on the Aluminum Post 3 Channel?

Yes. It is especially useful for closing the third channel when only two channels are carrying fence slats.

Can it be used on the Aluminum Side Post?

Yes. It can finish the compatible channel area on the Aluminum Side Post.

Can it be used with the Aluminum Gate Frame?

Yes. It can finish a compatible unused frame channel or conceal screws inside the channel.

Closing Channels & Concealing Screws

Why should I cover a channel that is not being used?

Closing the open channel creates a cleaner finished face and helps the post or frame match the surrounding powder-coated components.

Can this profile cover screws?

Yes. It can conceal compatible screws installed inside the post or frame channel after the slats have been secured.

Are the screws included?

No. Screws and installation hardware are sold separately because the required fastener depends on the post, frame, and project.

Does the cover snap into place?

Yes. The formed edges engage the compatible Alumission channel to create a clean snap-in finish.

Should I install the cover before or after the slats?

Normally it is fitted after the slats and channel screws are installed and checked, allowing the completed fasteners to be concealed.

Using the Cover as Slat Spacers

Can this cover be cut into spacers between slats?

Yes. The full-length extrusion can be cross-cut into short pieces and used as spacers between Alumission slats.

Can I choose any spacer size?

Yes. Cut the cover to the dimension required by the planned slat gap, subject to safe cutting and the complete fence or gate design.

Are specific spacer sizes available separately?

Yes. Alumission also sells specific pre-cut spacer sizes separately for faster installation and repeatable standard gaps.

Why use pre-cut spacers instead of cutting this cover?

Pre-cut spacers save fabrication time and provide repeatable sizes. Cutting this full-length profile is useful when the project needs a custom gap.

How do I keep the spacing consistent?

Use a verified cutting stop, cut every spacer to the same finished length, deburr the pieces, and check the complete pattern before assembly.

Will the cut spacer edges rust?

No. Aluminum does not rust like steel.

Dimensions, Ordering & Care

What are the profile dimensions?

The profile is 0.984″ wide and 0.331″ high, with a 0.803″ inside span and a typical 0.047″ wall thickness.

What material is the cover made from?

It is extruded from 6063-T6 aluminum and finished with a durable exterior powder coating.
