This is the replacement guide rail that aligns and supports the clamp arms during sealhead compression.

It ensures straight, controlled movement when compressing the negative spring.

You should almost never need this.

The rail is built to last and easily survives 15–20+ rebuilds.

This listing exists for lost parts or truly unfortunate accidents.

• Compatible with all versions of our screwless Sealhead Compression Tool
• Not compatible with threaded or screw-based compression tools

• 1× Replacement guide rail, ready to install

This is a replacement part, not a standalone tool.

If you’re unsure whether you need it, you probably don’t.

Use at your own risk. See our Terms of Service for details.
