Product Description

38cm Instalock Pad Holder (Rotobic Contractor) – Flexible Drive Block

Achieve an absolutely flawless, high-gloss shine on highly uneven or undulating commercial floors with the incredibly advanced 38cm Instalock Pad Holder (Suit Rotobic Contractor). When polishing older commercial buildings, the concrete or tiled floors are rarely perfectly flat. If you use a completely rigid, unyielding drive block, the polishing pad will 'bridge' over the low spots (leaving them dull) and grind far too aggressively into the high spots. This elite flexible drive block is meticulously engineered with a specialized 'Flexi Back' design. This heavy-duty rubberized layer allows the entire pad holder to pivot and contour perfectly to the microscopic undulations of the floor, ensuring 100% of the pad remains in constant contact for a spectacular, even shine.

Engineered explicitly to match the legendary performance of Rotobic commercial polishers, the 38cm (380mm / 15-inch) block features a premium, heavy-duty black 'Instalock' Velcro face. The thousands of microscopic hooks bite deep into the synthetic webbing of your floor pads, locking them immaculately in place at high RPMs. Designed with the precise, proprietary clutch plate required to securely mount to Rotobic Contractor series machines, these highly specialized floor polisher parts are the absolute cornerstone for professional contract cleaners who demand uncompromising, mirror-like results on highly challenging, uneven surfaces.

Who Is This Rotobic Flexi Back Pad Holder Ideal For?

The 38cm Flexi Back Pad Holder delivers contoured polishing and massive Velcro grip. It is highly recommended for:

Commercial Floor Restorers: Utilizing an advanced flexible drive block to achieve an immaculately even, high-gloss shine on extremely uneven, aging concrete or warped vinyl floors in older commercial buildings.
Rotobic Machine Owners: Upgrading or repairing their legendary Rotobic Contractor series floor machine with exact-fit, premium floor polisher parts that guarantee a secure, zero-wobble connection to the motor shaft.
Retail & Supermarket Cleaners: Relying on the 38cm footprint to smoothly glide white polishing pads across expansive showroom floors, completely eliminating 'dry spots' caused by uneven tiling.
School & Gymnasium Janitors: Safely stripping old wax and applying new sealant to highly sensitive timber halls, relying on the 'Flexi Back' to prevent aggressive gouging into high spots in the floorboards.

Key Features and Performance Benefits:

Advanced Flexi Back Design: The ultimate feature for uneven floors. A thick rubberized layer between the clutch plate and the block allows the entire pad face to pivot and contour. It keeps the pad perfectly flat against undulating floors, preventing dull spots and aggressive gouging.
Aggressive Instalock Velcro Face: The base of the block is covered in heavy-duty black hook-and-loop material. It bites violently into the synthetic fibers of commercial floor pads, ensuring they never slip or tear off at high RPMs.
Optimized 38cm (15-Inch) Footprint: The 380mm diameter is perfectly calibrated to hold standard 15-inch commercial floor pads, ensuring the heavy weight of the machine is perfectly distributed for high-speed buffing.
Rotobic Contractor Clutch Plate: Designed exclusively for a flawless fit. The integrated clutch plate is precisely engineered to lock securely onto the proprietary mounting shafts of Rotobic Contractor rotary machines.
Perfect Rotational Balance: Manufactured to absolute commercial tolerances. A perfectly balanced drive block prevents the machine from violently bucking or vibrating, drastically reducing the physical exhaustion of the operator.

Frequently Asked Questions

What is the advantage of a 'Flexi Back' pad holder?

Most cheap pad holders are rigid plastic. If your floor has dips and bumps, a rigid holder will miss the low spots and grind into the high spots. The 'Flexi Back' features a thick, rubberized pivot layer that allows the block to bend slightly, contouring perfectly to uneven floors for an even shine.

What is a 'Pad Holder' or 'Drive Block'?

A floor machine has a spinning metal shaft. You cannot attach a soft floor pad directly to metal. The Pad Holder locks onto the machine's shaft, and the bottom is covered in Velcro to securely grip and spin the synthetic floor pad.

What does 'Instalock' mean?

Instalock refers to the aggressive, commercial-grade black 'hook and loop' (Velcro) material glued to the bottom of the plastic block. The thousands of tiny plastic hooks bite violently into the synthetic fibers of your floor pad to stop it from flying off.

Will this block fit my Polivac or Hako machine?

NO. This specific pad holder features a highly proprietary clutch plate engineered explicitly to fit 'Rotobic Contractor' brand rotary machines. It will not click into standard PSA/Polivac or Quick Release machines.

What size floor pads should I buy for this 38cm block?

This 38cm (380mm) block is specifically designed to hold standard 15-inch commercial floor pads. Always ensure the pad is perfectly centered before turning the machine on to prevent violent wobbling.

Can I use this without a floor pad attached?

Absolutely NOT. The bottom of this block is covered in hard plastic hooks (Instalock). If you run this block directly on a floor without a thick, protective floor pad attached, it will instantly and permanently destroy your tiles or vinyl.

Why is my floor machine violently wobbling and shaking?

If you just installed a new pad, you likely did not stick it to the Velcro perfectly in the center. If a pad is off-center, it throws the heavy machine completely out of balance. Turn the machine off, peel the pad off, and re-center it.

Will the Velcro wear out over time?

Yes. Over hundreds of hours of commercial use, the tiny plastic hooks can become flattened by the immense weight of the machine, or become permanently clogged with stripped floor wax. When pads start slipping off, you must replace the block.

Can I use this block to strip heavy floor wax?

Yes! The Flexi Back design is phenomenal for stripping old wax, as it ensures the abrasive black stripping pad reaches down into the slight dips and hollows of older, uneven vinyl floors.

How do I clean the Velcro face?

You can use a stiff wire brush to gently comb out trapped hair and string from the Velcro hooks. If it is covered in wet floor wax slurry after stripping, hose it out with hot water immediately before the wax dries hard.

Can I use this for carpet shampooing?

No. To shampoo carpets with a rotary machine, you should use a specialized soft Nylon carpet brush, or use specific 'Bonnet' pads designed for carpets. Do not use standard hard floor pads on carpets.

Do you offer trade pricing for commercial floor restorers?

Yes, Freshway Supplies provides highly competitive volume pricing and trade accounts for commercial cleaning contractors, floor restorers, and appliance repair technicians outfitting their Rotobic machines. Contact us to establish your account.
