Light Duty, Medium Duty and Heavy DutyDesign and Features
Basic Components:
Typical Tension Latch Unlocked Position
How It Operates:
With drawhook engaged in strike, a downward force isapplied to handle causing drawhook to pull matingpanels together.
Positive lock is achieved when drawhook center isbeyond the common center line of the base and strike.Panels are held in place with tension load on latch.
To unlock, simply pull up on handle and disengagedrawhook from strike.
Operating Action:Over-Center and Under-Center.
There are two distinct operating actions for tensionlatches: over-center and under-center. Both providepositive lock-up.
Over-Center Locked Position
Over-center operating action rotates drawhook centerover base center and comes to a locked positionbelow the common center line of the base and strike.Its advantages are: low profile and large take-up.
Note: Strike must be mounted on same (or lower) panelplane as base of latch to insure positive lock-up.
Under-CenterOperating Action
Under-Center Locked Position
Under-center operating action rotates the drawhookcenter under the base center and comes to a lockedposition above the common center line of the base andstrike. Its advantages are: handle covers drawhook,short length and latch not sensitive to strike position.
Take-Up:
Take-up = A - B
Take-up is the distance latch pulls two mating sectionsor panels together.Over-Center

Adjustment:
Typical Threaded Drawhook
Many latches are provided with threaded drawhooks.Adjustment of drawhooks’ relative position to the strikeis made by rotating the drawhook.
Some latches offer bases with slotted mounting holes,allowing adjustment before fastening latch to panel.
Strength: Ultimate and Working.Ultimate strength is the load in pounds at which thelatch’s function is permanently impaired.Working strength is the maximum load in pounds whichcan be repeatedly applied without impaired function.
Special Purpose Bases:Many special purpose bases are available.
• Adjustable Slotted Base Versions.
• Radiused or Curved Base Versions.
• Reverse Base Versions.
• Mechanical or Weld Mounting Base Versions.Base versions available for mechanical (rivet or bolt)mounting or weld (spot or conventional) mounting.
• Low Profile Versions.
Special Purpose Drawhooks:Many special drawhook versions are availableincluding, narrow or wide width for space consideration.
• Extended and Special Profile Versions for GrippingWide Flanges or Spanning Raised Joints.
• Drawhooks with Lift-Spring — Drawhook automaticallysprings away from strike when disengaged and keeps inupright position while unlocked.
• Reverse Offset Drawhooks.
Secondary Lock Versions:Secondary lock provides added security againstaccidental opening due to vibration, shock or otherinfluences. Many secondary lock versions available.

Custom fastener rides in new autos.(Camloc article excerts as appeared in Machine Design)
A new air filter assembly was needed to fit into the shrinking underhoodspace of a major auto maker’s current model. The box cover, in particular,caused problems.
The air filter lid latch had to meet these requirements:• Have low profile.• Blend in with the underhood cosmetic theme.• Be custom-shaped to fit the housing.• Be free-standing with no base of its own.• Snap into an existing boss area without installation tools.• Be easy to operate by hand.• Corrosion resistant to withstand 96 hours of salt spray testing.• Be approximately 50 mm in length and 14 mm wide.
When this problem was presented to designers at Camloc Products, a47L latch was first suggested. It was a basic design of a low-profile latchmade of 17-7PH stainless steel. The steel is heat-treatable, which alloweda tempered drawhook to be made. The latch gets its locking capability fromthe metal’s temper, otherwise it would bend. Using this method allows thelatch to retain its shape while the drawhook itself acts as a spring.
Engineers liked the standard design, but modifications were needed.Initally, a rivet-type base had been used, but the housing was changed toallow the latch to snap in place. The handle had to be shortened to providemore of an arc that conformed to the shape of the air cleaner.
Final assembly was suitable for hand installation. The 17-7 PH stainlesssteel used in the latch is designed to withstand the combination of heat andmoisture found under the hood on the air cleaner.
Initially, a latch on acommunication switchcabinet was not clampingEMI/RFI gasketing, andnot closing properly.
This new latch solvedthe problem by providinga self compensating wire-form pawl designed tolead into a slot in thecabinet frame, providingsufficient clamping forceand vibration resistance.
(See Pawl LatchesH-49 through H-66).
Latch and handle assembly was modified from a previous design to fitan air cleaner.
This customdesigned latchhelped clean upcommunications.

When to Use Latches(Camloc article excerpts as appeared in Machine Design)
Latches are ideal for securing machine andequipment parts that must be opened orremoved frequently. Many can be easilymodified to suit special requirements,thereby eliminating the need for customdesigns.
Many parts on industrial andbusiness machines, agriculturaland construction equipment,aircraft, and road vehicles must beopened or removed frequently toallow periodic servicing. Examplesinclude hinged panels, doorsdrawers, windows, and safetyguards. All of these componentscan be secured with latches.
Latches allow quick accessbecause the holding or lockingelement—a hook, pawl, or bolt—releases immediately when ahandle knob, or tool socket isactuated. Typically, the holdingcomponent spans the jointbetween a panel or door and thesupporting frame. The latch basemounts either on the part to beopened/removed or the supportingframe. To lock a latch, a hook, pawl,or bolt must be engaged with astrike, hole, protruding lip, ordirectly with the mating jointmember.
Most latches are available inadjustable versions to accommodatea range of panel and frame thick-nesses, so manufacturing tolerancesusually are not critical. Such latchesusually have a self-compensatingdrawhook made of spring steel, aslotted mounting base, or a threadedelement to facilitate manual adjust-ment. Some adjustable latches canbe set to accommodate gaskets injoints. Latches can be attachedmechanically with rivets or screws,or they can be welded in place.
Latches are usually made of steel,
finished with a zinc-chromatecoating. Other finishes includechrome, black epoxy or polyure-thane paint, and black oxide.Another common latch material isstainless steel.Also, aluminum is sometimes usedfor latch bases where galvaniccorrosion may be a problem.
Actuators on hand-operated latchesinclude knobs, levers, or pushbuttons;tool-operated latches use a number ofdifferent fittings. Such tool-operatedlatches are opened with screwdriversor hex wrenches.
Many versionsA seemingly endless variety of latchesis available. The reason for so manydifferent components is that latchsuppliers routinely modify standardfasteners to suit special requirements.For instance, a certain overcentertension latch is available in more tan200 variations. Some of the modifica-tions or options are a secondary lockor hasp, extended drawhook, reversedhook, right-angle mounting base, basewith raised pivot, and even specialfinishes or materials.
Standard latches can be sorted intofour general categories:• Handle-operated latches• Rotary-actuated latches• Slide latches• Panel latches
Design considerationsLatching requirements should beconsidered at the onset of newproduct development so that
standard fasteners can beselected if possible. If littlethought is given to latching untilthe product design is wellunderway, the only solution then isto extensively modify standardlatches or design entirely newlatches, both of which increasecosts.
Today’s design standards call for anaesthetically pleasing appearanceon the outside of machines andequipment. Consequently, latchesoften must have flush, unobtrusiveactuators.
Human engineering also plays animportant role in latch selection.Thus, consideration should be givento who must operate the latch, forwhat purpose, under what circum-stances, and how often. Forexample, if a door on a piece ofheavy construction machinery mustbe opened often by an operatorwearing gloves, a large knob orlever is needed. On the other hand,if an access panel on a computerperipheral need be removed only bya service technician, then aninconspicuous tool-operated latch isappropriate.
Electronic equipment poses specialrequirements for latches. Forinstance, latches not only mustsecure access panels and doors,but also may have to providesufficient clamping force to com-press RFI/EMI metalized gaskets.These gaskets prevent radiofrequency or electromagneticinterference from entering or beingemitted by equipment. In addition,panels on certain electronicequipment must mount flush withouter surfaces, slam closed, andallow only limited access. Suchrequirements usually can be metconveniently by specifying pull-release and trigger-release panellatches, which are available off theshelf.
Shown are typical heavy duty tension latches detailed in this section.See individual pages for size and performance variations.
