The Spike+ false bottom is for use with their Spike+ line which uses TC fittings. For their standard Spike kettle line that uses NPT fittings please see HERE.
Design Features:
All stainless design; no Silicone gasket to make a seal
Low profile design; extremely low dead space (<.25gal)
Excellent filtering due to dual stage filter design; 99.9% grain filtering efficiency
TC Pickup tube, gasket and clamp are included
False bottom and pick up tube are Made in the USA
2 Stage Filtering: Stage 1: Filters through top plate's optimally engineered sized laser cut slits
Stage 2: Bottom ring supports the grain weight while also filtering the wort again before it reaches the pickup tube
**False bottoms are not designed to filter pellet hops in the boil kettle. Instead you'll want to create a whirlpool to center the hop material and then drain using a side pickup**
