Product families
Metal details for the parts buyers specify most.
Browse by function first. Dimensions, construction, material and finish are confirmed against each project brief.
Locks
Insert, twist and clasp lock directions for bags and accessory programs.
Rings & fittings
D-rings, O-rings, rectangular rings and bridge fittings for attachment points.
Hooks & chains
Swivel hooks, spring rings and chain-related components for moving connections.
Decorative hardware
Logo plates, enamel directions and visual details developed around the design.
Buckles & adjusters
Pin buckles and adjuster-style parts where strap fit and movement matter.
Attachments
Eyelets, handle attachments, studs and small metal components for complete sets.
A clear development path
Move from design intent to a part your team can approve.
Early decisions about structure, fit, load, opening and closing, spring behaviour and finish can prevent avoidable rework later.

Read the drawing, use case and critical interfaces.
Sampling
Review appearance, dimensions and the first physical direction.
Tooling & trial

Production & assembly
