Sawstop RT-LFT Four-Post Router Lift with Lock

Key Features

Precise Lift ControlThe chain-synchronized four-post lifting system keeps movement even across the plate, so height changes stay controlled and repeatable when you are dialing in a cut. Positive LockOnce the bit height is where you want it, the lock helps hold that setting in place. That matters when you are making repeat passes and do not want the setup drifting. Fits Multiple RoutersThe SawStop RT-LFT Four-Post Router Lift with Lock accepts router bodies from 3-1/4 inches up to 4-1/4 inches, and includes reducer collars for common sizes so setup is less of a hassle.

Overview

The SawStop RT-LFT Four-Post Router Lift with Lock is a router table accessory built for accurate above-table router adjustment in a SawStop router table setup. This is a router lift designed for above-table height adjustment, bit setup, and repeatable routing work. Model Number RT-LFT. If you want cleaner setup changes and more control over bit height than a fixed plate gives you, this is the part that makes the table feel like a serious production tool instead of a compromise.

What matters most here is how the lift moves. SawStop uses a chain-synchronized four-post lifting system, which means the plate raises and lowers in a controlled, balanced way rather than fighting you from one side or twisting under load. In real use, that helps when you are sneaking up on a profile cut, setting a flush-trim bit exactly where it needs to be, or making fine height changes for joinery. The positive lock gives you another layer of confidence once the setting is dialed in.

The top plate measures 11-3/4 inches x 9-1/4 inches and is built to fit SawStop router tables. SawStop also calls out an aluminum router plate paired with a 3-3/4 inch phenolic insert ring. That combination matters because the plate needs to stay stable and flat, while the insert ring helps size the opening around the bit for cleaner support at the table surface. It is a straightforward design, but it is the kind of detail that separates a decent router table setup from one that is actually pleasant to use.

Router fit is flexible enough for a wide range of full-size routers. The lift accepts router diameters from 3-1/4 inches up to 4-1/4 inches, and SawStop lists fit for 3.25 inch, 3.5 inch, and 4.0 inch to 4.2 inch routers. The included reducer collars in 3-1/4 inch and 3-1/2 inch sizes help adapt common router bodies without making you chase extra parts right out of the gate.

From a build standpoint, the RT-LFT is clearly aimed at heavy-duty precision work. The images show the four-post hardware, chain drive, and lift mechanism openly enough that you can see this is not a flimsy stamped accessory. It is the kind of router lift you buy because you plan to leave it in the table, keep a good router mounted, and use it for real edge profiling, pattern routing, joinery, and repeat work instead of occasional hobby-only use.

Compatibility is simple and important: this lift is made for the SawStop Router Table. That explicit fit matters because router lifts are not one-size-fits-all. If you are building out a SawStop router table station and want the matching lift designed around that platform, this is the correct accessory to look at.

Who should buy it? Woodworkers, cabinet guys, trim carpenters, and serious DIY users who care about precise routing adjustments and want above-table convenience. If you already own or are buying a SawStop router table, the RT-LFT makes the setup more capable and easier to fine-tune. If you are just looking for the cheapest way to hang a router under a table, this is probably more lift than you need. If you want accurate, repeatable control, it makes a lot more sense.

Built for Fine Router Height Adjustments

This is the part that gives your router table setup the control most users are actually after. Instead of reaching underneath and guessing, you can make measured changes from above the table.

• Chain-synchronized four-post lifting system for balanced movement
• Positive lock helps hold the chosen bit height during repeat work

Designed Around the Mechanism, Not Just the Plate

The big advantage here is not just that it lifts. It is how evenly it lifts. The mechanism is built so the plate stays controlled while you make small changes, which is what matters for pattern bits, edge profiles, and joinery cuts.

• Four-post design supports stable movement across the lift
• Precision above-table elevation measurement and adjustments are called out by SawStop
