Model LEB-04, J style blade type, is an architecturally styled 4" deep louver designed with smooth, clean lines that visually compliment any structure’s exterior styling. Available in channel or flanged type, the 4" deep frame installs easily in most common wall configurations. Suitable for use in exhaust and low to medium velocity intake applications, the blade design features a rear water baffle and provides good protection against general weather conditions, with low pressure drop characteristics and a high free area. Reinforcing bosses run the full length of each blade for superior strength.
