Fixture Columns

Clamp multiple parts or fixtures to these columns to speed up your machining process. Also known as tombstones, they have multiple faces for building dense, efficient setups. Each face is precision-machined for accurate positioning. Made from cast iron, these columns are rigid enough to limit vibration and stabilize your workpieces during machining.

Blank


Square	Rectangle	Cross

Blank columns can be customized to fit your application. Machine them with your own holes, T-slots, or other mounting surfaces.

Square—Square columns have four equal faces for balanced machining on each side.

Rectangle—Rectangle columns have two wide faces for larger setups and two narrow faces for smaller ones. The narrow faces can also help reduce tool interference.

Cross—Cross columns have four equal faces, similar to square columns, but cutouts at each corner give you more tool clearance.

Grid


Square	Rectangle	Cross

Grid columns have industry-standard hole patterns. The holes are lined with a precision bushing and a threaded insert to help locate fasteners, so you can clamp parts accurately and securely. Both are hardened to resist wear. These columns also come with a plastic chip plug for each hole—plug unused holes to keep debris from clogging them or causing damage.

Square—Square columns have four equal faces for balanced machining on each side.

Rectangle—Rectangle columns have two wide faces for larger setups and two narrow faces for smaller ones. The narrow faces can also help reduce tool interference.

Cross—Cross columns have four equal faces, similar to square columns, but cutouts at each corner give you more tool clearance.

Retrofit Socket Kits for Tubular Light Bulbs

Revive your fluorescent strip lights. These sockets replace aging ones and eliminate the need for ballasts. Instead, they power the bulb from one end. Use them with ballast bypass LED bulbs. They’re an economical alternative to replacing the ballast and outfitting your light with socket-ready LED bulbs.

Remove the old sockets and ballast, connect the spring-clamp terminals to your power supply, and bend the bracket tabs to fit the width of your fixture housing.
