Festool 577220 LEYSYS-FT1 35cm (13-3/4-in) Spirit Level – Fits in Systainer Handle

Key Features

Accurate Layout ChecksThis spirit level gives you both horizontal and vertical vials with measuring accuracy of +/- 1.0 mm/m, so you can check level and plumb without switching tools. Systainer-Ready StorageThe Festool level nests in the handle of a Systainer3, which keeps it protected, easy to carry, and right where you need it instead of loose in the truck or drawer. Built for Round StockThe prismatic contact surface sits cleanly on shafts and pipes, which makes this a lot more useful than a flat level when you are checking round material.

Overview

The Festool 577220 LEYSYS-FT1 35cm (13-3/4-in) Spirit Level – Fits in Systainer Handle is a compact aluminum spirit level built for fast, accurate layout and setup work. This is a spirit level designed for checking level and plumb during installation, setup, and finish work. Model Number: 577220. If you already work out of Systainers, the big advantage here is simple: this level stores directly in a Systainer3 handle, so it is always with the case instead of getting lost in the bottom of a box.

Festool gave this level one horizontal vial and one vertical vial, with stated measuring accuracy of +/- 1.0 mm/m. In real use, that means it is made for the kind of alignment checks you do constantly on site or in the shop: cabinets, tool setup, machine alignment, trim, fixtures, and quick checks on work surfaces. The front has a metric scale and the reverse has an inch scale, so you can grab a quick reference measurement without reaching for a tape for every small check.

The profile is made from naturally anodized aluminum with ABS details, which matters because a level like this gets handled, tossed into cases, and used around benches and machines. Aluminum keeps it light at about 0.6 lb, while still giving it the rigidity you want in a straight measuring tool. At 35.4 cm / 13.93 in. long, it is compact enough to live with your system, but long enough to be genuinely useful for setup and installation work.

One of the more practical details is the prismatic contact surface. That surface is shaped to sit properly on shafts, tubes, and pipes, so you are not balancing a flat level on round material and hoping for the best. If you do mechanical setup, shop fixture work, rail alignment, or any kind of install where round stock shows up, that detail makes this tool more versatile than a basic pocket level.

There is also some real jobsite practicality in the way Festool designed the storage. The LEYSYS-FT1 is meant to store securely in the handle of a Systainer3 for transport. That is a smart move for anybody already using the Festool storage platform, because it turns a small measuring tool into something you are far less likely to misplace. One important limitation is worth knowing up front: it does not fit in the handle of Systainer3 ToolBoxes or the Systainer3 ToolBag.

This is not trying to replace a long framing level. It is a compact precision level for tradespeople and serious DIY users who need a reliable setup tool that travels with their system. Cabinet installers, finish carpenters, woodworkers, remodelers, and anyone running Festool Systainers will get the most out of it. If your day is full of small but important alignment checks, this is the kind of tool that saves time simply because it is accurate, durable, and always close at hand.

Always Right With the Systainer

The whole point of this level is convenience without giving up accuracy. It rides in the Systainer3 handle, so it stays with the system you are already carrying to the job.

• Designed for secure storage and transport in a Systainer3 handle
• Helpful for quick machine, bench, and installation checks when you do not want to dig through a full toolbox

Works on Flat and Round Surfaces

A flat contact edge is fine until you need to check a tube, shaft, or pipe. The prismatic base gives this compact level a more stable contact point on round material.

• Prismatic contact surface helps the level sit properly on shafts and pipes
• Useful for shop setup, fixture work, and installation tasks where round stock shows up

Compact Size, Real Measuring Utility

This is a small level, but it is not a throwaway accessory. The dual vials, aluminum body, and built-in scales make it a practical daily-use measuring tool for fine setup work.

• One horizontal vial and one vertical vial for level and plumb checks
• Metric scale on the front and inch scale on the reverse

Pro Tip

Use the LEYSYS-FT1 in its standard orientation when checking level or plumb. Festool specifically notes the vials are not intended for inverted-position measurements, so flip the workpiece or your setup instead of flipping the level.
