The product that you have referenced is just an anchoring base for a bait station to attach to and it does not come with the tamper resistant stations or the bait. Below is a link that will take you to the product page that has the tamper resistant bait stations and the bait sold together in kits. (be sure to pay attention to the descriptions as some stations are for mice only and rats cannot fit into them):
The Protecta Load-N-Lock Anchoring System – Protect Sidekick will fit only the Protecta Sidekick stations. It will not fit the EVO Express, Ambush, or any other stations. The EVO Express Bait Stations already have a weighted block inside the station, so you would need another weight system with it. The Protecta Ambush is the EVO station without the brick inside.
