Boaters and sailors listen up - if you've got Spinlock Deckvest lifejackets, these re-arming kits are essential safety items to keep on hand. Each kit contains the specific CO2 cylinders needed to re-arm your automatic inflation lifejacket after it's been deployed or tested. There are different kits for various Deckvest models - the DW-RAK/75 for ALTO 75N belt packs (uses 2x16g cylinders), DW-RAK/100 for Cento Junior (20g), DW-RAK/E170 Pro Sensor for Elite models (33g), and several others for different weight requirements and lifejacket types. It's super important to match the correct kit to your specific lifejacket model - check your owner's manual if you're unsure. Having these on board means you can quickly get your lifejacket back in service if it accidentally inflates or after you've done maintenance testing. Safety first out on the water! These are genuine Spinlock parts so you know they'll work perfectly with your equipment. Don't get caught with a non-functional lifejacket - keep a spare re-arming kit in your marine safety kit.
