The Pet Net, LLC now offers The Original Pet Net and the newly redesigned Pet Net Plus. The NEW Pet Net Plus was designed for customers: 1) needing a barrier to reach nearly to the ceiling 2) intending installation in a rear cargo area 3) whose vehicles do not have upper attachment points in the \"right\" place for The Original Pet Net and 4) for small cars. If any of these factors pertain to your circumstances, consider The Pet Net Plus instead of The Original Pet Net. The New Pet Net Plus has its own Amazon listing. (http://www.amazon.com/gp/product/B00NRZ9G82) THE ORIGINAL PET NET is designed to fit many cars, vans, SUVs and trucks. Installation and removal are quick and simple using a bungee attachment system. Assess your vehicle for upper attachment points before ordering The Original Pet Net. Typical upper attachment points are handles or seatbelt fixtures. If your vehicle lacks upper attachment points, i.e., a handle or seatbelt housing near where you want to install the unit, or if the attachment point is too low, consider THE NEW PET NET PLUS. For sizing, measure from upper attachment point toward the floor estimating the vertical coverage desired.
