Pipe Flange Lockouts

Lock pipe blinds in place to prevent gas, steam, or chemicals from flowing through your line. These lockouts block access to flange bolts, keeping your team safe during pipeline maintenance. They have slots for four padlocks, so up to four people can lock out at once. Using them helps you comply with OSHA 29 CFR 1910.147, which requires the use of lockouts during work on pressurized pipelines.
These lockouts adjust to fit a range of flange sizes and bolt positions. Made of stainless steel and aluminum, they resist corrosion over time. A bright red powder-coated finish makes them easy to see when they’re in place.
