In Brief
Keys and locks for silo trailer hose lockers are matched by closure type, not trailer brand. PHS Magnum in Chorula near Opole keeps the full range of popular types permanently in stock: butterfly locks, 8 mm external and internal square, spike-profile and Feldbinder type. We serve mixed fleets (Spitzer, Feldbinder, Kässbohrer and others) from a single offering. Courier shipping across Poland, the EU and the DACH market. The most reliable way to match a part is a photo of the lock — ask for a quote.
Introduction
A hose locker is a storage compartment — most often a tube on the silo trailer chassis — used to carry the pneumatic hoses, couplings and pipes needed to discharge bulk material at the receiver’s site. To stop the equipment from falling out while driving, or getting dirty or stolen when parked, the locker is secured with a key or lock. It’s a detail of everyday trailer operation, unrelated to the pneumatic system, yet a real nuisance when the lock seizes or the key goes missing.
Trailers of different years and manufacturers use several popular locker closure types — which is exactly why we approach this category from a mixed-fleet perspective rather than a single brand. We keep the full range of types permanently in stock: from butterfly locks, through 8 mm square locks, to spike-profile closures and the Feldbinder type. Workshops and fleets running trailers from multiple manufacturers can therefore source a matching key or lock in one place, without needing to check whose badge the trailer carries.
Specification
Keys and locks for hose lockers in all popular types:
| Closure type | Description |
|---|---|
| Butterfly | closure operated by rotating a butterfly-shaped element |
| 8 mm external square | key fits over a protruding 8 mm square on the lock |
| 8 mm internal square | key slides into an 8 mm square socket on the lock |
| Spike-profile | closure opened with a spike-profile key |
| Feldbinder type | lock and key in the Feldbinder-type design |
Selection comes down to identifying the closure type fitted to the locker and matching a compatible key and, if necessary, a complete lock. For the 8 mm square versions, the way the key engages — external or internal — is also decisive. If the closure type is uncertain, the most reliable method is to send a photo of the lock.
Brand compatibility
Locker closures are matched by type, not trailer brand, so one offering covers many manufacturers:
- Spitzer (SF/SK) — hose lockers on the chassis of SF and SK series aluminium trailers, with popular closure types.
- Feldbinder (EUT/KIP) — lockers on the chassis of the horizontal EUT tank and the tipping KIP silo; Feldbinder also uses its own closure design (the Feldbinder type).
- Kässbohrer (K.SSK/K.SSL) — hose lockers with the typical closure types.
- Other brands — lockers from various manufacturers are often fitted with locks of the same type, including the Feldbinder type, so the same range of keys and locks fits.
Selection means establishing the closure type (butterfly, 8 mm external or internal square, spike-profile, Feldbinder type) and supplying a compatible key and, if needed, a complete lock. In fleet operation it often makes sense to standardise closure types within one trailer or across the fleet — the driver then doesn’t have to juggle key sets, and replacing lost keys is simpler.
How to choose a key or lock — step by step
Matching a locker part doesn’t require knowing the trailer’s brand or year — what matters is the closure type. The process looks like this:
- Identify the closure type — butterfly, 8 mm external square, 8 mm internal square, spike-profile or Feldbinder type.
- For an 8 mm square, determine how the key engages — whether it fits over a protruding square (external) or slides into a socket (internal).
- Assess the lock’s condition — if the mechanism works, a key alone is usually enough; if it’s seized or corroded, we supply a complete lock.
- Send a photo of the closure — the most reliable matching method when the type isn’t obvious.
- Consider standardising — within one trailer or across the fleet, unifying the closure type simplifies key management.
The table of closure types and descriptions is in the Specification section above. We combine keys and locks in a single shipment with locker covers and other wear parts from the catalogue.
