# Slide & Lock Mechanism

The *Slide & Lock* mechanism is an exclusive mounting system developed for the LineMaster 2.4GHz, designed to enable quick physical swapping between different models—*no tools or additional adjustments required*.

This mechanism relies on a sliding piece that inserts into the front of the handle. It consists of a base and three screws, allowing you to adjust both the **line spacing** and **line trim**. Each model should have its own dedicated piece, ensuring the physical setup for that specific model is preserved.

To use it, simply slide the piece onto the guide at the front of the handle and push it firmly until you hear a *click*—that sound confirms it’s securely locked in place. To remove it, press the release button while sliding the piece out.

You can download the `.stl` file for the sliding base *completely free* below, in case you want to make custom modifications or improvements. Just make sure to keep the **outer dimensions** and **top shape** unchanged to ensure the piece slides properly and the *Slide & Lock* mechanism continues to function safely and reliably.
