Trimco K39 Series Finger Guards

The K39 finger guard mounts to the door stop on the hinge side and stays put through the swing. The heavy gauge vinyl bends as the door closes and tracks the door as it opens, so the hinge edge gap stays covered at every point in the swing. It is non-handed, so the same part works on a left or right hand opening and you do not have to specify handing when you order.

K39 guards are made in any length up to full door height, and 92 inches is the most commonly ordered height. That covers a standard 7 foot (84 inch) door leaf plus the frame area above it, which is why it is the usual pick. If you have taller openings, the guard can be made to match full door height.

The K39 is ADA compliant. It sits on the hinge side of the opening at the door stop rather than on the pull side face, so it does not add projection where a person approaches the door. It is a commercial rated product intended for daycare facilities, nurseries and pre-schools.

Hinge side only. The K39 protects the gap between the door and the jamb on the hinge edge, which is where the shear point is and where a child's fingers get pinched when the door closes. It does nothing for the latch edge or the bottom of the door, so if your incident was on the strike side you need a different product.

The vinyl itself is clear, so it reads neutral against any door color or decor. What you match is the metal reinforcement along the stop edge, and that comes in four finishes: 605 bright brass, 606 satin brass, 613 oil rubbed bronze, and 630 satin stainless steel. Pick the one that matches the hinges and pulls already on the opening.

Yes, and the K39 is built for that. It is non-handed, so one part number covers every door regardless of swing direction, and the clear vinyl means you are not matching a color per room. The only variables to fix across the facility are the length (92 inches suits most standard openings) and the metal finish on the stop edge, so a single length plus finish combination usually covers a whole floor.

The guard attaches to the door stop, not to the door face or the hinge itself, so no door prep or hinge change is involved. Because it mounts on the stop, confirm your frame has a usable stop surface on the hinge side. Trimco publishes a mounting template for the K39 (template T11739) that gives the hole layout for the install.

The K39 is a commercial product, not a residential add-on. The vinyl is heavy gauge and flexes with the door rather than resisting it, and the stop edge, which is the part that takes the fastening load and the daily abuse, is metal reinforced. That reinforced edge is what keeps it from tearing loose on a door that cycles constantly in a nursery or pre-school.
