Linear drain assemblies and methods of use

A linear drain assembly comprising:

• a drain body including:
• a permanent structural cover:
• a first drain channel formed below the cover and extending in a longitudinal direction along the drain body;
• a first slotted inlet defined in the cover and located toward a sidewall of the first drain channel, the first slotted inlet extending in the longitudinal direction along the cover and being in fluid communication with the first drain channel;
• and
• an outlet structure intercepting the drain channel;
• and
• at least one end attachment attachable to a longitudinal end of the drain body, the at least one end attachment including;
• a second drain channel in fluid communication with the first drain channel of the drain body, the second drain channel having a closed end defining a curvature;
• and
• a second slotted inlet extending in the longitudinal direction along the at least one end attachment and in fluid communication with the second drain inlet, the second slotted inlet forming a continuation of the first slotted channel,
• wherein the closed end of the second drain channel is arranged to direct debris moving through the second drain channel toward the second slotted inlet.
