Does bulk insert lock table?

TABLOCK. Specifies that a table-level lock is acquired for the duration of the bulk-import operation. A table can be loaded concurrently by multiple clients if the table has no indexes and TABLOCK is specified. By default, locking behavior is determined by the table option table lock on bulk load.
