Vent Hardware Kit For NB20 Enclosures

These Vent Hardware Kits are ideal for situations where you need to drill out the rivets used to secure the vent screens and need to re-secure them afterwards. The vented enclosures require shorter screws as they are only securing the filter screens and do not need the extra length needed for securing a fan.The 14-18" Kits include four #6 Stainless Steel Screws and four #6 Speed Nuts & the 20" Kits include four #6 Stainless Steel Screws and four #8 Speed Nuts.
