FCSOTSPS Shower Door Bottom Seal – 3/8-Inch Thick, 36-Inch Each – 2-Piece M Type & D Type Dam Set

Keep your frameless shower clean and dry with a precise water barrier

Powered by a two-piece sealing system, this FCSOTSPS set is designed for 3/8-inch frameless glass doors and provides a reliable edge-to-floor seal along a full 36-inch length per piece. The kit includes an M Type shower door seal and a D Type dam, with the D Type intended to widen coverage and fill larger bottom gaps. When paired, they offer a seamless barrier that helps minimize splash and keep the shower floor dry, even on busy mornings or after a thorough wash.

The seal is crafted from clear, durable polycarbonate, chosen for long-lasting clarity and resistance to color change. The accompanying dam is made from acrylic, with a half-round profile that fits flat floor surfaces and targets gaps up to 1/4 inch. This thoughtful combination lets you tailor the fit to modest or wider thresholds, without compromising a clean, minimal appearance on your frameless glass enclosure.

installation is quick and straightforward thanks to a tool-free approach. No adhesive is required: simply align the new seal beside the door, press to snap into place, and enjoy. Before you start, remember to remove the red adhesive backing film if it is present on your model. The result is a smooth, friction-friendly edge that allows the door to glide with little resistance while maintaining a dependable water barrier.

What this set delivers in everyday use

• Superior water containment: a continuous barrier that helps prevent leaks at the base of frameless doors.
• Clear, durable materials: polycarbonate remains visually unobtrusive while resisting color changes over time.
• Versatile gap coverage: the D Type dam bridges wider bottom gaps and works in concert with the M Type seal.

• Easy, tool-free installation: snap-fit design avoids messy adhesives and residue.
• Long, consistent length: each piece runs 36 inches, with no splicing or micro-gaps to contend with.
• Soft fins for smooth operation: the fins reduce door friction and help maintain a quiet, controlled seal.

These features combine to support a tidy bathroom routine, a drier shower floor, and a more comfortable entry and exit from your glass enclosure. While individual results will vary with door shape and bathroom layout, the system is designed to offer practical improvements in splash control and maintenance.
