DURA POUCH Size L Holster for Castles Technology S1F4 PRO
DURA POUCH Size L is a textile holster from Duratis that fits the Castles Technology S1F4 PRO – the PRO edition of the Castles Technology S1F4 Android smart POS with a built-in receipt printer. It lets waiters and event staff carry the Castles Technology S1F4 PRO hands-free and take it out in a second, without the risk of drops, scratches or a lost device.
Will the Castles Technology S1F4 PRO fit?
We matched the Castles Technology S1F4 PRO to DURA POUCH Size L because its internal space – up to 240 x 90 x 60 mm – holds this payment terminal firmly without squeezing it. A holster that is too big lets the device bounce while you walk; one that is too small slows you down every time you reach for it.
Features that save time
With the DURA POUCH there is nothing to unfasten. The Castles Technology S1F4 PRO slides straight in and out, and a polyamide lining reinforces the edges against abrasion and tearing. A pen pocket is built in and the hip belt is included in the box.
Materials and warranty
Cordura® fabric gives this holster up to ten times longer lifespan than standard materials. Lab-tested abrasion resistance exceeds 50,000 cycles, tear and tensile strength are tested to EN ISO standards, and the fabric repels water. At 45 grams the holster is barely noticeable on the belt during a long shift. Every Duratis holster is made in Europe and covered by a 5-year warranty that includes tearing.
Where the Castles Technology S1F4 PRO holster works best
Typical applications of the DURA POUCH Size L holster with the Castles Technology S1F4 PRO include handling payments in parking, transport and ticketing services and taking payments on the shop floor and in queue-busting. In each case the benefit is the same: the payment terminal is always within reach, both hands stay free, and the device is protected from drops, dust and everyday wear – which means fewer repairs and fewer replacement devices.
For the Castles Technology S1F4 PRO we also offer the DURA POCKET holster with Velcro closure and extra pocket. For bulk orders, logo customisation or a sample for your Castles Technology S1F4 PRO fleet, contact the Duratis team.
