Harbor Freight has recalled 454,000 jack stands because they have the potential to sudden drop when under load.

The recall affects both three-ton and six-ton models with an item number of 56371, 61196, and 61197. The heavy-duty steel jack stands from Pittsburgh Automotive could malfunction if the pawl is disengaged from the extension lifting post, which could cause serious injury or property damage.

The recalled jack stands that have a model number of 56371 can be identified by locating the item number on the label on the top of each unit while the model numbers 61196 and 61197 can be identified by locating the item number on the yellow part of the label on the base of each unit.

Harbor Freight is urging consumers that have purchased the jack stands to stop using them immediately. Because of the coronavirus, Harbor Freight said the affected jack stands can wait to be brought to a store when they reopen, and stay-at-home orders have lifted. Customers that have purchased the recalled jack stands will receive an in-store gift card equal for the retail price of the product.

Harbor Freight issued the recall in conjunction with the National Highway Traffic Safety Administration.
