- Fits perfectly with your Intrepid 4x5, Graflex, or Linhof? (see full list below). This reel allows simultaneous development of up to 6 sheets of large format film in the compact Paterson System 4 Uni Tank (PTP115).
- No darkroom needed for chemical changes: Thanks to the integrated light trap, you can change developer, stop bath, and fixer under dim light without risking the film.
- Safe film handling without scratches: The precisely crafted design minimizes the risk of emulsion damage and prevents films from overlapping during agitation.
- Efficient workflow: The MK2 design optimizes the process compared to standard inserts and saves time handling the Paterson funnel.
Note:
This reel is designed exclusively for the Paterson Universal Tank (PTP115). In larger tanks (PTP116, PTP117, PTP118), the light trap loses its function.
The reel is a modified version of a freely available design by "Evan Dorsky" (CC-BY) on Printables.

- 1x MK2 4x5" large format film development reel
- 1x Integrated light trap
Technical specifications:
- Material: Chemical-resistant plastic
- Capacity: Up to 6 sheets of large format film (4x5 inch)
- Tank compatibility: Paterson Universal (PTP115)
- Construction: MK2 design with improved light guidance
Description:
This development reel enables professional processing of large format sheet films in your existing Paterson system. The integrated light trap ensures safe chemical changes outside the darkroom. The optimized geometry develops films evenly and without contact between them.
Compatibility:
- Paterson Universal (PTP115)
- Paterson Multi-Reel 3 (PTP116)
- Paterson Multi-Reel 5 (PTP117)
- Paterson Multi-Reel 8 (PTP118)
Note: The light trap fits and functions properly in the Paterson Universal (PTP115). In the larger tanks, the light trap loses its function, so you must change chemicals in complete darkness there.
