Frequently Asked Questions

Super Lube is a patented, multi-purpose synthetic lubricant, containing SYNCOLON® (PTFE) particles held in suspension. Super Lube lasts longer and outperforms conventional petroleum-based greases and oils. It comes as a grease, an oil with PTFE, and a light-weight oil without PTFE. Packaging includes tubes, grease cartridges, aerosols, bottles, pails, and drums.

Super Lube Grease and Oils are exceptionally pure because they are synthetic, giving very stable and predictable properties. Petroleum-based machine and gear oils are refined from crude and contain impurities that cannot be removed. These impurities interfere with film strength and wear protection, form deposits at high temperatures, and solidify at low temperatures. Petroleum greases use lithium, calcium, or sodium thickeners in petroleum oil.

SYNCOLON® (PTFE) is Polytetrafluoroethylene — one of the lowest-friction materials known. In Super Lube, PTFE particles fill surface irregularities of mating parts and compact (like snowflakes in a snowball) to form a smooth, lubricated surface. Benefits include improved anti-wear, waterproof performance, resistance to acids/alkalis, and temperature resistance up to 750°F. Super Lube’s patented formula keeps PTFE in constant suspension for even application.

Compared to lightweight petroleum oils, Super Lube Lightweight Oil offers improved wear resistance, withstands high temperatures, remains free-flowing in low temperatures, and is excellent for drip/mist applications and as a food-grade chain lubricant.

No. OLFA rotary mats are specifically designed for OLFA rotary cutters and rotary blades. Snap-off or utility blades will damage rotary mats. OLFA cutting mats are professional quality and twice as thick as OLFA rotary mats.

ULTRAMAX blades use a special double-honing process for superior sharpness and are about 25% sharper than standard OLFA blades — ideal for precise, finished work.

Load OLFA CMP-2 Heavy Duty Compass Cutter with an LH-20B Heavy Duty Snap-Off Hook Blade and cut from the bottom of the carpet for a clean plug (a straight blade creates a bevel).

No. Rotary blades are tungsten carbide tool steel and very sharp. Sharpening risks nicking the blade and damaging fabrics.

They reference fixed positions from an original safety cutter design. Since the 1979 rotary cutter, they’re just a historical feature.

Rotary Circle Cutter: Premium pro tool with ratchet handle (reduces wrist fatigue), RH/LH use, cuts 1-7/8” to 8” circles, no stabilizer required.

CMP-1: Occasional use; with paper-backed fusible webbing, cuts perfect circles up to 6” diameter.

It depends on material and frequency of cutting. To maximize life, always use an OLFA Rotary Mat and apply only enough pressure to cut your fabric.

When used properly with sharp OLFA blades, cuts tend to “close” and the surface remains smooth thanks to the mat composition.

Wipe with lukewarm water + dish detergent, let sit 5 minutes, rinse, towel dry. Repeat as needed.

Unfortunately, no. Follow care instructions to prevent warping. Repurpose warped mats for paper projects.

Yes — UTC-1 Auto Lock Retractable Utility Knife (heavy-gauge stainless blade channel, HandSaver grip, 5-position retractable blade). Works with standard, rounded-tip and hook dual-edge blades.

Hold the cutter with the back pointed away. Press down on the blade slide and push it out the back. Carefully remove the old blade from the peg, place the new blade on the peg, and slide the assembly back into the handle.

• Maintenance: Inspect for damage/wear; keep moving parts clean.
• Check the blade: Start jobs with a fresh sharp segment — dull blades are unsafe.
• Use cutters only for cutting: Don’t hammer/pry; misuse can cause failure and injury.
• Blade extension: On snap-off blades, never extend past the next segment line; use one segment at a time.
• Blade lock: Ensure the ratchet/lock is engaged before cutting.
• Stay alert: Learn proper use and limits; always pay attention.

A 2 or 3 Mil plastic film with an adhesive side that sticks to carpet.

A 3 Mil plastic film with adhesive for hard wood, tile & ceramics. (Linoleum does not always work.)

Adhesive on the outside of the roll for easier forward application with little or no bending down.

Up to 45 days.

No, as long as you remove it within 45 days.

Yes — avoid storing rolls in humid areas.

No.

The adhesive pulls too hard on wool fibers.

A lens (single or compound) that increases the apparent size of objects by adding focusing power so you can move closer than ~10 inches and see more detail.

The “X” value indicates image size vs. the unaided eye at ~10 inches (e.g., 2X = twice as large, 3X = three times, etc.).

The distance for clear focus and maximum magnification. Approximate examples: 2X ≈ 5", 5X ≈ 2", 20X ≈ 1/2".

The area visible at one time; primarily inversely related to power (higher power → smaller field). See example PDF: B&L Magnifiers.

The distance you can move toward/away and keep focus; higher power yields shorter depth of field.

Conditions such as macular degeneration create central blind spots that obstruct recognition. Magnifying the object reduces the relative obstruction so letters/objects can be identified more easily. Magnification can be provided by making the object larger (large print), moving closer, or using optical/video systems.

Measure from the edge of the door to the center of the hole (one simple measurement).

From the outside of the door, the hinge side determines handing. Swing direction doesn’t matter.

22mm is equivalent to a 1" bore.

Yes. To lock from outside, turn the knob. To unlock, enter the combination and turn the knob.

One combination per lock at a time.

Yes — the 1150 & 2835 series.

Grade 2.

Yes — trim plates cover the standard 2-1/8" hole.

Fit 1-3/8" – 2". Extension kits available for thicker doors (up to ~5").

Deadbolts include adjustable latches. Latch (spring latch) applications are not adjustable — specify 2-3/8" or 2-3/4".

Available in the 2000 series (2200, 2210, 2230, 2435, 2500, 2210 DC, 2230 DC). On double-sided locks, key override is only on the outside.

Yes — in the 2000 series. Double-sided locks require two oversize knobs.

Yes.

Yes — on the mechanics of the lock (finishes not covered).

Both are deadbolts with interchangeable bolt pieces. The L2000 is smaller, has fewer digits, and uses a thumb-turn throw; the 2210 has a round knob.

Yes — all field-changeable except the 1150 series.

AB, BB, SC, JB (see product listing for specifics).

See the listing for the lock you’re interested in.

No — check related items on that lock’s page.

No. Lockey key overrides are unique to these locks; cylinders are non-removable and not interchangeable.
