How it connects
Overlap the strap and engage its integral double tabs with the matching openings to lock it in position. This is a mechanical support connection, with no fluid seal.
Male and female halves
The strap mates to itself rather than to separate male and female fittings. “Hermaphroditic” describes this self-mating arrangement; it is not a verified manufacturer interface designation.
Usually connects to
- An overlapping section of the same compatible interlocking hanger strap
Common sizes
- Verified Oatey example: 3/4 in. wide, 28-gauge galvanized steel, supplied in a 10 ft. roll. These describe the strap stock, not a standardized tab size; tab dimensions and pitch were not verified.
Where it is used
Plumbing pipe supportSuspending piping from joists or raftersVertical or horizontal pipe support
How to recognise it
Look for a metal hanger band with repeated double-tab features as well as nail holes. Confirm the product is described as interlocking or self-fastening with a double-tab design; generic perforated banding or unrelated supports in listing photos are insufficient.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| Plain perforated metal hanger strap | The target has integral double locking tabs for self-fastening; nail holes alone do not establish this interface. |
| Strap-to-joist nail or screw attachment | That uses a separate fastener through a hole into the structure; the target joins overlapping strap sections. |

Good to know
The Oatey strap example uses self-interlocking tabs. No standardized tab geometry or cross-brand compatibility is established.
