The Mafell LS 103 Ec 5-7/8 in. Chain Mortiser Kit is a complete, heavy-duty timber-framing solution configured for 2.0 in. mortising. Built around the high-output 2500W, 240V LS 103 Ec mortiser, this kit includes the FG 150 mortising guide stand for precision plunging, plus a complete 2.0 in. chain setup with an extra mortising chain for maximum uptime.

Designed for fast and accurate mortise cutting in solid wood and glulam, the LS 103 Ec features a lightweight housing—weighing just 19.2 lbs. without the stand—making it highly maneuverable on the jobsite. The tool features an ergonomic handle and switch layout to reduce fatigue, while the rapid chain tensioning system allows for quick adjustments or replacements without removing the protective guard.

The included FG 150 mortising guide stand transforms the tool into a highly stable precision mortiser, allowing for safe plunging up to 5-7/8 in. (150 mm) deep. Complete with a secondary depth stop and adjustable fence, the guide ensures flawless repeat cuts. With the 2.0 in. bar, sprocket, and two 2.0 in. chains, this kit delivers exceptional durability for wider, heavy-timber mortising applications.
