Top-Sticks, Slot-Sticks or Preformed Slot Wedges

Nomex and DMD Slot Wedges, Top Sticks and Slot Sticks at Associated Gaskets

Half used bundles of Preformed Slot Wedges are a common sight in any motor rewinding workshop. Sometimes known as top-sticks, slot-sticks or simply as wedges, these are a popular choice for filling slot voids in smaller types of electric motors that don’t require a machined epoxy, polyester or magnetic solution.

Throughout our decades of experience working with the electric motor rewinding industry, Associated Gaskets has learned that there’s one key feature that matters above all else when it comes to these wedges; having them when you need them. To help, we’ve committed to holding each type in our range of preformed slot wedges in stock in a range of sizes.

This page breaks down the differences between each of the 3-main materials stock by AG and provides a brief overview of what each is used for. Whether you require curved or square Nomex wedges, 180°C rated DMD or good old-fashioned wood slot sticks for your repair job, we’ve got you covered.
