LiftMaster 11-10197 Take-Up Bolt Shaft Replacement Part 3/8 x 4 Trolley
The LiftMaster 11-10197 take-up bolt shaft is a service replacement part for the trolley/take-up area of select commercial door operator rail systems. On a commercial trolley operator, small rail hardware can make a big difference in how the trolley tracks, tensions, and transfers movement from the operator to the door arm. This part is listed as a 3/8 inch x 4 inch take-up bolt shaft and is used where the rail or trolley assembly requires this exact shaft style. It is a maintenance part rather than a control board, receiver, or electrical accessory. Customers usually look for this item when the original take-up bolt shaft is bent, missing, worn, seized, or damaged during trolley or rail service. Because commercial operator rails vary by operator family, rail length, and production generation, the safest way to identify this part is by the operator parts breakdown and the old shaft dimensions. If the existing hardware is damaged, compare the old part with the parts diagram instead of matching only by general appearance.

Technician Note
A worn or incorrect take-up bolt shaft can cause rail noise, trolley binding, poor travel, or repeat damage to connected rail hardware. Replace damaged rail hardware only after checking that the trolley, rail, chain/belt drive components, and door balance are not causing the failure.
Before Ordering Checklist
- Confirm the operator is a compatible commercial trolley door operator, not a residential opener.
- Match the old shaft to 3/8 inch x 4 inch sizing.
- Check the rail or trolley parts diagram for K11-10197, 11-10197, G115015, 1110197, or 115015.
- Inspect the trolley, rail, fasteners, and door arm for related wear before reassembly.
- Do not force a similar hardware-store bolt into a commercial trolley assembly if the shoulder, length, or thread style is different.
Professional Advisory
Commercial door operator rail service should be handled with the operator disconnected from power and the door secured. If the trolley is jammed, the door is out of balance, or the operator has structural rail damage, have a qualified commercial door technician inspect the system.
