ABSTRACT:
A lateral extension of a shackle end and a lock body securely engage a hasp therebetween. Broadening the shackle end or tapering the shackle provides lateral extension. A shroud or encasement around the hasp, shackle and lock body provides additional security. A sliding shroud with attached shackle fits over the lock body encasement. Alternately, an extension of the lock body encasement itself serves as a shroud with a removable shackle, or a swing plate covers the hasp. Pivoting or rotating arms may secure the shackle to the lock body. Close contact with the hasp and encasement protects against tampering.
