HASPS –The Closing Mechanism for Padlocks

Neck bolts, surface bolts, offset surface bolts and other padlockable bolts can be grouped as laminated steel plate locking bolts. These locks use different shaped bolts to secure applications including roll up entry and drive-in doors. Laminated bolt locks have varying throw lengths at different positions. The standard bolt lock is almost flush with the surface. The offset bolt lock can be more than one inch away from the surface to accommodate an obstruction such as a parting strip. Locking bolts are available in a variety of sizes and accommodate different types of strike plates. Most locking bolts can be locked in the secured position and the unlocked position.

Garage door hasps incorporate a steel bolt with two padlock eyes welded onto the base. One eye is for the locked position with the bolt extending into the jamb. The second eye is the unlocked position to prevent accidental locking. Major Manufacturing’s Garageblok is a jimmy-proof shielded garage door hasp with built-in lock shield and 5/8” diameter hardened steel bolt. The handed housing is manufactured from 3/16” thick zinc chromate plated steel. The Garageblok is anchored to the door with four supplied 5/16” carriage bolts, washers and nuts.

Angle hasps or padlock eyes provide closing capability for double swinging or sliding doors, wood gates or even cabinet doors or drawers. They are available in varying sizes and styles. Padlock Eyes are probably the most inexpensive type of hasp available. They are normally sold without mounting screws.

The two-part American Lock A810 Gate Hasp is designed to attach to chain link gates and fencing poles that are 1-5/8” or 2” in diameter, where the opening is between three and six inches. The locking mechanism is a sliding fastener that interconnects to the two halves of the gate hasp. To lock the gate the fastener is slid to the stop position. Once in position, a padlock shackle up to 7/16” in diameter and at least one inch vertical shackle clearance secures the fastener and the gate from opening. Four carriage bolts secure this gate hasp in place.

Pacific Lock’s PAC-LINK is a higher security option to the cable or chain locks that can be used to secure gates or fences. PAC-LINK incorporates a hockey puck padlock with a stainless steel investment casting that fits beneath and around the padlock. One end of the chain is bolted into the casting. The other end of the chain slides into a slot in the casting. The hockey puck fits into the casting, on top of the two ends of the chain, and offers a high level of security because of the inability to attack the ends of the chain or the base of the padlock. PAC-LINK will accept up to one half-inch thick link chain. The casting can be welded or bolted onto a fence or gate.

A variation of the angle hasp is the van or vending machine hasp. The Master Lock No. 770 Solid Steel Hasp is a two-piece hasp with exposed mounting bolt holes and side protection for the padlock. The No. 770 hasp is designed to be operated using a “hockey puck” style of padlock. The “Hockey Puck” style padlock uses a straight shackle to provide the locking mechanism. This way the padlock connection to the hasp is concealed. This hasp has a welded metal partial ring that surrounds all but the lock cylinder of the padlock preventing prying and other forms of force.

A specialized application of the van lock is the Pacific Lock Truck-Puck Locking System (TPLS). The compact TPLS is designed to secure box truck roll up doors. Like the van lock system, the TPLS locking device leverages the strengths of a “hockey-puck” lock to secure a truck roll-up door. Unlike the van lock system, the TPLS is portable and can be moved from one vehicle to another. The two components of the TPLS, the Lock Body and Locking Bolt, combine an anti-saw shield with 1/4” thick steel. A hardened steel hockey-puck lock is welded onto the front completely hiding the shackle. When the TPLS is installed, the rollup door handle cannot tilt up in order to unlatch the door. The TPLS is available with a hockey-puck lock that can also be fitted with Small Format Interchangeable Cores or Key-in-Knob style cylinders.

Safety lockout hasps are designed not specifically for security, but more for agreement control. These aluminum, steel or stainless steel scissors like hasp have multiple openings; usually six punched into each half of the hasp. Padlock shackles can slide into each of the slots and be locked. When more than one padlock is locked onto a safety lockout hasp, all of the padlocks must be unlocked and removed in order to regain control. Example applications for the safety lockout hasp is to be connected to an energy disconnect switch or controls in order to keep equipment inoperable.
