Plaster J Stop (Milcore)


The Plaster J Stop is a formed metal product, which is available in Aluminum, Copper, Galvanized Steel, and Stainless Steel. It serves as a termination point for plaster cement and is available with or without 3/16" Weep Holes.

Attach Plaster J Stops to the framing members with nails, screws, or other approved fastening methods. Each installation of the Plaster J Stop must be examined to determine the best positioning of the weather resistive barrier (Vertical and Horizontal Installations differ in their placement of the building paper). Lath must entirely cover the attachment flange.

The Plaster J Stop comes in 10' lengths and can be ordered in a variety of ground sizes. The fastening flange (dimension "A") and the Ground Leg (dimension "B") are available in multiple sizes and custom widths. The Plaster Key (dimension "C") is 3/16" standard, but can be ordered in a larger size, relative to the other two flanges' dimensions. Please specify the sizes needed on the order form below.
