Tired of measuring for keyhole slots, making multiple surface marks, and still having objects that are crooked or will not mount? The Keyhole Companion solves this by attaching to keyhole slots and marking where the fasteners need to go on the surface. No measuring, generating templates or guessing.

Keyhole Marking Tool

“If you’ve struggled to hang picture frames or other wall-mounted décor with keyhole hardware, this Accu Mount Keyhole Slot Marking Tool Set is just what you need. It quickly installs on the piece you want to hang, and when you press it against the wall, a small mark is made in the exact location you need to place the screw. There are lots of hacks out there that will allow you to do the same thing but if you want an easy way to make these marks grab one of these keyhole markers online….”

To ensure the Keyhole Companion works with the widest range of keyhole slots and hardware, three built-in interchangeable interfaces are included. Simply select the interface that matches the slot type, and screw it into the center post.

Any TIPS when using the Keyhole Companion?

1) Choose the correct interface for the slot type.

2) Push the product to the end of the slot while tightening.

3) Product needs to be perpendicular to the surface when tightened (if tilted, spacers can be used to make it perpendicular).

For KEYHOLE SLOTS ON A SMALL RAISED SURFACE (like a pedestal) the tool tilts when tightened. How do I prevent that?

An adapter can be made using a 7/8” diameter or larger fender washer with #6 or 5/32” or larger center hole (available at hardware stores). Simply unscrew the flat interface, put it through the washer, and re-install the interface with the washer.

Using FLAT NARROW ADD-ON KEYHOLE SLOT hardware, the Keyhole Companion tilts when tightened. How do I prevent that?

An adapter can be made by placing a spacer (like a wood coffee stirrer) adjacent to each long side of the hardware. The Keyhole Companion will then rest on the spacers and tighten perpendicular to the object surface.

Using FLAT ROUND ADD-ON KEYHOLE SLOT hardware, the Keyhole Companion tilts when tightened. How do I prevent that?

• For surface mounted, a spacer will typically be needed under one end of the Keyhole Companion in order to have it tighten perpendicular.

• For recessed, two spacers may be needed, one of them long enough to fully bridge the recess diameter.

What do I do if there’s NOT ENOUGH GRIP-RANGE (interface extension) to mount the Keyhole Companion in the keyhole slot?

Insufficient grip-range (interface extension) can occur if the keyhole slot material is too thick, if a recess is cut too deep, or as a result of the use of spacers. The remedy is to partially unscrew the interface to increase the product grip range.

WORKS WITH KEYHOLE SLOTS and SAWTOOTH HANGERS – Using the included interfaces, the hanging tools work on all keyhole slot materials and most keyhole slot and sawtooth bracket configurations, including for keyhole molded-in (plastic), cut-in (wood, plastic or metal), add-on hardware (surface mounted or recessed). Accommodates thicknesses from thin metal to 3/8″. [See website FAQ for any keyhole slot configuration that creates difficulty].
MARKS VIRTUALLY ANY SURFACE – Comes with non-drying (confirmed so far 5 years) black and white ink to mark both light and dark surfaces. The caps store ample long-lasting ink for more than 1000 uses. Works on hard, soft, smooth, and rough/textured surfaces. Ink marks can be removed with a Magic Eraser or denatured alcohol.
RECESSED, SELF-INKING MARKER – When the tools are mounted, ink is automatically transferred from the ink reservoir in the snap-on cap to the marking pad. The recessed marking pad is a unique design feature that ensures the surface remains free of unwanted marks while positioning the object. The only mark on the surface is the fastener location mark that comes from the push-to-mark action.
