Overview
Two waterproof tackle cases from KastKing's HyperSeal line, sized to hold 3600 and 3700 style tackle trays and finished in orange.
Tackle boxes marketed around 3600/3700 tray compatibility follow a common sizing standard, letting anglers swap in trays built to those dimensions from other brands too. A sealed closure keeps stored lures and hooks dry and rust-free between trips, which matters most for anglers who store gear in a boat or leave it exposed to weather.
- Compatible with 3600 and 3700 size tackle trays
- Waterproof HyperSeal closure
- Two piece set
- Orange colorway
Who it's for
Suits anglers who already use 3600 or 3700 size tackle trays and want a sealed case to keep them dry and organized. Less useful for anyone using a different tray size standard.
Pros and cons
- Fits standard 3600 and 3700 size trays
- Sealed design guards against moisture and rust
- Sold as a two piece set
- Only fits trays built to 3600/3700 dimensions
- Trays themselves may be sold separately
Performance notes
The HyperSeal design relies on a gasket closure to keep water out of the case, which protects hooks and lures from rust and keeps trays from sliding during transport. How well it performs depends on the gasket staying clean and the latch fully closing on each use.
