Quickly & easily mark fastener mounting locations for frames, shelving, power strips, electronic equipment & more with the Keyhole Companion. The patented/patent pending Keyhole Companion was conceived while battling to mount a power strip with keyhole slots. Mounting an object using keyhole slots is frustrating at best, requiring either multiple measurements or creating some form of template. Each of these options is time consuming and in many cases requires a second try. When the marks are off, the object will not mount or will not be positioned as desired.The Keyhole Companion solves this problem by securely attaching to the keyhole slots of almost any object, making the object itself into a template and then marking exactly where the fasteners need to go on the surface. No measurements & no guesswork. Keyhole Companion works with most keyhole slot configurations and marks on a variety of surfaces making a tedious and error-prone task quick and easy.Ideal for use in mounting the following types of objects if they have keyhole slots or if keyhole slot hardware can be added: - Power strips/surge suppressors - Ethernet switches/networking equipment - Uninterruptible power supplies - Floating shelf/floating shelves - Floating shadow boxes - Parts cabinets/organizers - Electronic photo frames - Clocks and weather stations - Plaques - Telephone and small appliance bases - Decorative and utility items - DIY items with keyhole slots formed using a keyhole router bit - Any items where keyhole slot hardware can be added, such as picture/art frames and mirrors for secure hanging (for example, for earthquake safety). ## Features - FEATURES & BENEFITS ** The only keyhole slot marking tool with a recessed marker – leaves no unwanted marks while positioning an object in contact with the surface ** No measuring or templates needed to mount items with keyhole slots ** Spring-loaded tools hold in place while tightening ** Self-inking marker ** Long-lasting ink (now 5 years) will make more than 1000 very visible marks ** Storage rack holds all components in one place ** Professional quality with metal internal components - 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. - BUILT-TO-LAST: Commercial-grade Design using Metal Internal Components - Use for many years on any keyhole slot-enabled objects including Power strips, Surge protector, Floating shelves, Picture hanging (including on slanted walls), Corbels, Small parts organizer, Network switch, Power tool battery chargers, DIY keyhole router bits, Add-on keyhole slot hardware, etc. WARRANTY: 1 year ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07X5BQ8PX | | ASIN | B07X5BQ8PX | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #88,984 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #568 in Picture Hanging Hardware | | Color | Black, Red | | Customer Reviews | 4.5 4.5 out of 5 stars (2,697) | | Customer reviews | 4.5 4.5 out of 5 stars (2,697) | | Date First Available | 23 September 2019 | | Date First Available | 23 September 2019 | | Item Package Quantity | 1 | | Item Weight | 142 g | | Manufacturer | Accu Mount Tools | | Manufacturer | Accu Mount Tools | | Material | Metal | | Product Dimensions | 18.8 x 12.7 x 3.81 cm; 141.75 g | | Product Dimensions | 18.8 x 12.7 x 3.81 cm; 141.75 g | | Size | 2 Count (Pack of 1) | | Special Features | Non Toxic | | Tool Tip Description | Thin | ## Images ![Keyhole Companion Marking Tool Set – Mount/Hang Items that have Keyhole Slots Without Measuring; Tools Mark Fastener Locations on Walls.

How do I prevent that?** A: 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. **Q: Using FLAT NARROW ADD-ON KEYHOLE SLOT hardware, the Keyhole Companion tilts when tightened. How do I prevent that?** A: 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. **Q: Using FLAT ROUND ADD-ON KEYHOLE SLOT hardware, the Keyhole Companion tilts when tightened. How do I prevent that?** A: • 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. **Q: What do I do if there's NOT ENOUGH GRIP-RANGE (interface extension) to mount the Keyhole Companion in the keyhole slot?** A: 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. ## Frequently Bought Together - Keyhole Companion Marking Tool Set – Accurately Mark Keyhole Slot Fastener Locations without Measuring, Templates, or Creating Unwanted Wall Marks – for Keyhole Slots and Hangers - Go Hang It!
