The Imperial VT0640 is a professional-grade 4-inch roof vent cap engineered for high-performance exhaust in residential and light commercial HVAC systems. Constructed from heavy-duty galvanized steel with a weather-resistant black powder-coated finish, it features a seamless one-piece base designed to prevent leaks on shingled roofs. The integrated anti-gust backdraft damper prevents air infiltration, while the removable plastic screen protects against birds and rodents. This versatile vent cap is ideal for bathroom exhaust fans and can be adapted for dryer venting applications by removing the internal screen.

General Ledger Coding

General Ledger Coding is a value added service provided for you at no additional cost.

General Ledger Coding makes accounting easier by providing you with a calculated total of purchases based on your General Ledger Codes.

In addition to traditional General Ledger Summary provided at time of invoice, we can also provide quotes and order acknowledgements with General Ledger Coding as well. We also give you the ability to change a GL Code for one or all items for renovation projects that may utilize a single GL Code. We can also code any of our "extended inventory" items with your General Ledger Code at the time of quote, order confirmation and invoicing as well. We can code our item numbers directly to your GL Codes should our item categories not align directly with your GL Code Categories.

Please contact us if you wish to implement our General Ledger Coding feature.
