Riser Section Binds on a Sleeve or Floor Opening

The riser section is binding at the floor opening and is still supported. I checked the visible sides and the connector is contacting the sleeve. Do you want it lowered for measurement before we change anything?

Stop if

Stop before changing structural support, rated construction, equipment handling, specialty materials, weatherproofing, engineered movement details, or manufacturer-specific requirements without the responsible direction.

Watch out

Do not ram, pry, hammer, or grind the opening while the section is suspended.

Check

current drawings and approved details
grid/floor/location and measured conditions
photos showing the installation condition
relevant manufacturer, structural, architectural, or finish information
what has already been checked
