Harvia Protective Sheath M Black

Harvia WL400 Protective Sheath

The Harvia WL400 protective sheath is designed and approved for use with Harvia M1, M2, M3, and M3 SL wood-burning sauna heaters. This protective shield significantly reduces the required safety distance to combustible materials, providing added peace of mind—especially in compact or space-conscious sauna environments.

The WL400 attaches directly to the heater and conforms to its shape, creating a slim, integrated appearance. Constructed from durable steel sheet and finished in black, it delivers a clean, functional solution that enhances both safety and visual cohesion.
