Remington Choke Tube question

can a Remington choke tube that is marked Trap Extra Full be used in a Standard or Express barrel ??, I the reason I ask is because I just received 3 tubes that i purchaes off ebay and THE SELLER had written acrosse the top not to use them in a standard or express barrel, I tried them in my 11-87 and my 870 and they both seemed to fit ok , any reason not to use them with the smaller shot sizes? thanks
