The 1637 is one of the most popular larger sized Peli cases. We use them for our 6u flyracks but they have tons of other uses too. 
 
Available in 4 colours with the option to add Pick 'n' Pluck Foam or Padded Dividers.
 
(Although we only hold stock of a small range of Peli products we're are more than happy to quote for the full Peli range. Just get in touch for bespoke pricing on any of the Peli range.)
