Definition: A one-hole strap hanger is a piece of hanging hardware installed on the back of picture frames. It consists of a flat metal strap with a single mounting hole for securing to the frame, and a loop or slot for attaching hanging wire or for direct placement on wall hooks.

Overview

This type of hanger is one of the most common and straightforward solutions for light- to medium-weight frames. Its simplicity makes it easy to install, while its design provides a stable point for connecting hanging wire or engaging directly with a nail or hook on the wall.

Characteristics

Mounting Hole: One screw hole for secure fastening to the frame's back or moulding.
Strap Design: Flat metal strap distributes pressure and resists bending.
Loop or Slot: Provides attachment point for hanging wire or hooks.
Materials: Typically steel or zinc-plated metal for strength and corrosion resistance.

Uses in Framing

One-hole strap hangers are frequently used on smaller frames, posters, or decorative pieces where lightweight, dependable hanging hardware is sufficient. They are usually paired (one on each side of the frame back) and connected with picture hanging wire for balanced suspension.

Advantages

Easy to install with minimal tools.
Secure and reliable for light to mid-weight artworks.
Compatible with both wire hanging and direct hook placement.

Limitations

Not as strong as two-hole strap hangers, which provide better load distribution.
May twist or loosen over time if improperly installed.
Not recommended for very large or heavy frames.

Best Practices in Use

Install two hangers, one on each side of the frame's vertical rails, at equal distances from the top for balance.
Ensure the screw is sunk into solid wood or reinforced moulding to prevent pullout.
Pair with high-quality hanging wire and wall anchors rated for the weight of the frame.
For heavier frames, consider using D-ring hangers or Z-clips instead.
