The SawStop TSI-SLD Standard Lock Down Insert is a replacement table saw insert for SawStop cast-iron saws using standard 10 inch saw blades. This is a table saw accessory designed for creating a zero-clearance opening around the blade for cleaner cuts and better workpiece support. Model Number: TSI-SLD.

What matters here is fit. A zero-clearance insert closes up the gap around the blade, which helps support fibers at the cut line and can improve cut quality on plywood, veneered stock, and other materials that like to chip out. SawStop states this insert creates a zero-clearance fit on first use, so once installed and cut to the blade, it is matched to your setup instead of leaving a wide factory opening.

The construction is better than a throwaway accessory. SawStop uses a precision-machined phenolic core with a low-friction, wear-resistant melamine surface on the top and bottom. In plain terms, that means the insert is built to stay flat, slide material smoothly, and hold up better over time than a cheap insert that gets fuzzy, swells, or wears unevenly.

Jobsite practicality is built into the details. Positioning screws help dial in a solid, precise fit in the table, while the positive locking latch allows tool-free operation when you need to remove or reinstall the insert. That is the kind of feature you appreciate when changing setups, checking the blade area, or swapping accessories in the middle of a project.

This insert is also made to work with SawStop safety components already on the saw. It includes pre-formed clearance slots for the SawStop blade guard and riving knife, plus dual metal wear plates for anti-kickback pawls. That means you are not giving up compatibility with the saw's safety hardware just to get the tighter cut support of a zero-clearance insert.

Compatibility is specific, which is a good thing because inserts are not one-size-fits-all. The SawStop TSI-SLD Standard Lock Down Insert is compatible with SawStop ICS, PCS, and CNS cast-iron saws, and it is not compatible with the SawStop JSS-120A60 or CTS-120A60. If you run a SawStop cabinet saw or contractor saw in that cast-iron platform and use a standard 10 inch blade, this is the right kind of insert to keep on hand for cleaner work and a more dialed-in setup.

Who should buy it? Woodworkers, cabinet installers, trim carpenters, serious hobbyists, and shop owners who care about cut quality and proper fit. If you are the kind of user who notices the difference between a decent setup and a really sorted-out saw, this accessory earns its spot fast. It is not flashy, but it solves a real problem every time the blade meets the stock.
