Joist Hanger Types: Mini, Jiffy, Face-Fix and Masonry Uses
The right joist hanger starts with the connection: what is supporting the joist, and how is the hanger designed to attach to it? A timber beam, a built-in masonry detail and an engineered joist system need different checks.
Names overlap. “Jiffy” is a familiar description for a timber hanger style; “face-fix” describes an attachment arrangement. “Heavy duty” says little without the model’s technical data. Use those names to find the right family, then check the actual connector.
Which type does what?
| Type | Where it fits into the choice | Before buying |
|---|---|---|
| Mini joist hanger | A compact seat and side flanges for a specified timber connection | Actual timber width, permitted depth, load and fixing pattern |
| Standard-leg jiffy hanger | A formed timber-to-timber hanger with longer side legs than a compact mini design | Model dimensions and the supporting timber connection |
| Long-leg hanger | A different leg arrangement where the approved connection calls for it | How the legs are fixed or formed; extra length is not automatic extra capacity |
| Multi-truss / heavy-duty hanger | A connector family for specified timber or truss arrangements | Exact model and published connection performance |
| Masonry joist hanger | A design intended for a specified masonry support detail | Wall material, bearing, masonry above and installation instructions |
When would I look at a mini hanger?
A mini design can be useful where a compact timber connector is specified and its dimensions suit the available connection. Our Fixings Direct mini joist hangers include several timber-width options. Measure the actual timber between the hanger sides: the outside flange width is a different dimension.
Do not choose a mini hanger simply because the joist is short or the project is small. Joist depth, span, loading and the supporting member all affect the connection design. An apparently light application can still require a different connector.
Standard-leg and long-leg jiffy hangers
Compare the leg height, seat and fixing arrangement on the drawing. Our Fixings Direct standard-leg jiffy hangers are a separate choice from other leg arrangements. The 150mm B340/150 jiffy hanger is a wider standard-leg model with a 333mm overall leg, rather than the B460 long-leg range. Check where the legs must be fixed and whether the manufacturer permits any bending or wrapping detail.
Do not cut off a leg, bend a flange to fit or leave out specified fasteners to work around an obstruction. If the drawn connection will not fit the supporting timber, the connector choice needs revisiting.
Timber face-fix and masonry hangers are different
A timber face-fixed hanger connects to the face of a supporting timber member using its specified fasteners. A welded masonry hanger with a top flange is made for a different support detail. Do not fit the latter to an existing wall using an improvised row of wall plugs.
For example, TIMCO A2 stainless masonry joist hangers need the masonry installation requirements for that exact model. Confirm bearing, the wall specification and any requirements for masonry above the flange. An existing-wall retrofit may need a separately designed solution.
Face-fix or concealed-flange hangers?
Compare the flange arrangement and access for the specified fixings. For example, our 100mm face-fix hanger and 100mm concealed-flange hanger are separate products. The concealed-flange version has its face plates folded inwards; it is not a standard hanger modified on site.
Check the exact model drawing, supporting-member dimensions and fixing access. A concealed appearance does not establish suitability or load capacity.
Is a truss clip the same as a joist hanger?
No. A joist hanger has a seat supporting the end of a timber member. A TC44 truss clip is a connector for fixing trussed rafters to wallplates and restraining crossing timber members. It should not be selected as a substitute for a joist-end support because it has a similar U-shaped appearance.
Our TC44 listing is supplied as a pack of 10. Use its TC range sheet and the specified fixing detail for the intended restraint connection.
What does “heavy duty” tell me?
It helps identify a range, but it does not give a universal load rating. The Fixings Direct Ultra and multi-truss ranges must still be selected by model, dimensions and technical data. For engineered I-joists, doubled members or unusual angles, use the joist-system designer’s details.
Once the type is settled, our joist hanger sizing guide covers actual timber width and depth. Then check the specified hanger nails or connector screws alongside the connection drawing.
