Is your door slamming shut, closing too slowly, or refusing to latch? Start by watching it close from a fully open position. Check its speed through the main swing and again as it approaches the frame. These observations will help you decide what to inspect before making adjustments.<\/span><\/p>

If the door moves too quickly through most of its swing, check the main closing speed. If it moves normally and bangs into the frame at the end, check the latch speed. If it catches or rubs, the closer may not be the problem.<\/span><\/p>

This guide covers surface-mounted hydraulic door closers commonly used on commercial doors and some residential entry doors. Storm-door tube closers, concealed closers, and powered door operators need their own model instructions.<\/span><\/p>

Which Door Closer Setting Should You Check?<\/h2>

First, look for loose hardware, damage, or fresh oil around the closer. If anything looks wrong, address it before testing or adjusting. Otherwise, open the door to about 90 degrees, keeping within its normal opening range, and let it close while you stand clear of the swing.<\/span><\/p>

Adjust one setting at a time. If the sweep is working properly and only the final movement is too fast, there is no reason to change every setting.<\/span><\/p>

Before Adjusting a Door Closer, Check the Door<\/h2>

Move the door slowly by hand, without disconnecting the closer arm. Some resistance from the closer is normal. Look for scraping, catching, or a sudden increase in resistance as the door reaches the frame.<\/span><\/p>

Check the hinges, latch, strike plate, threshold, and weatherstripping. A sagging door or a latch that misses the strike needs attention before you add closing force. Turning a speed valve does not repair those problems.<\/span><\/p>

Inspect the closer body, arm connections, and mounting brackets too. Stop if the body moves against the door, an arm is bent, or oil is leaking. Use the manufacturer’s repair instructions and approved parts, or have a door-hardware technician assess the problem. Do not bend a damaged arm back into shape.<\/span><\/p>
