These reconfigurable 3-way elbows are designed to fit 1/2 inch Schedule 40 PVC pipes and offer versatility for your construction projects. With the ability to adjust the angles to both 22.5 and 45 degrees, these fittings can be used to create pitched roofs, custom-designed frames or other structures that require precise angles. Each fitting is designed to function as the basis for up to four different elbows and one Y-fitting, providing great flexibility in the design. By using the included sleeves and caps, you can adjust the angle as needed, which simplifies the construction of complex shapes. They are an ideal complement to conventional plumbing fittings and are particularly well-suited for projects where precise angles are critical, such as building a greenhouse or other outdoor structures that require a specific slope for water drainage or aesthetics.
