Tidel Vend Tubes are available for the old style TACC IIR and new style Tidel TACC IIa Safes as well as the Tidel Sentinel Safe. All we need is the serial number of the Tidel Safe to determine the correct Tidel TACC Tube to send. There is a minimum on how many Tidel Coin Tubes you can buy, We recommend the box of 20 Tidel Vend Tubes because you will need them over time. The price is per box of 20 Tidel Vend Tubes. The older Tidel TACC IIR Safes use the smaller Tidel Vend Tubes, While the newer Tidel TACC IIa Safes use the Larger Tidel TACC Tubes. And since Tidel Safe does not sell Tidel TACC Tubes individually, We have to sell Tidel Vend Tubes in boxes of 20 Tidel Coin Tubes. Please contact me if you require larger quantities of 50 TACC Tubes or 100 TACC Tubes.
