HoleMole #5 Core Hole Former – 9.5–12.5in (241–318mm)

Description

HoleMole #5 Core Hole Former – 9.5–12.5in (241–318mm)

• Designed for 241–318mm openings: HoleMole #5 is the largest standard size, fitting concrete core holes between 9.5 and 12.5 inches in diameter.
• Reinforced for wider openings: Integrated stability ribs improve the rigidity of the larger former during positioning and filling.
• Permanent steel support: Manufactured from durable 16-gauge galvanised steel to form a dependable base beneath the selected repair material.

HoleMole #5 is the largest standard Mole in the HoleMole core-hole filling range. It is designed for concrete openings from 9.5 to 12.5 inches in diameter, equivalent to approximately 241 to 318mm. This makes it suitable for major redundant service openings and large drilled cores where conventional boarding from beneath can require significant access, labour and coordination.

The expandable former is inserted from above. Its folding perimeter sections collapse sufficiently to pass through the opening, then open below the slab. Pulling upwards on the connected rod draws the Mole into position, after which the reusable stand and SpeedNut hold it steady while the selected repair material is guided into the opening through the Speed Chute.

To suit its wider diameter, HoleMole #5 is manufactured from 16-gauge galvanised steel with formed stability ribs for added stiffness. Bendable positioning tabs support correct placement and approved wall applications. Each unit includes one 24-inch threaded aluminium rod. Cable Glands UK offers UK-wide supply and product support from Manchester.

Important: Supplied as 1 × HoleMole #5 with 1 × 24-inch (approximately 610mm) threaded rod. Reusable HoleMole tools, the Wall Applicator and all repair materials are excluded unless expressly listed.

Key Features

Key Features of HoleMole #5

• Largest standard Mole size: Designed for concrete core openings between 9.5 and 12.5 inches, approximately 241 to 318mm.
• Reinforced large-diameter design: Formed stability ribs increase stiffness across the broad former.
• Bendable tabs: Aids positioning and compatible vertical-opening work where the method is approved.
• One-way collapsible sections: Allows the large former to pass through the core before opening beneath the slab.
• Installed from the upper level: Helps remove routine underside boarding from the workflow for suitable large-opening repairs.
• 16-gauge galvanised steel: Creates a permanent supporting base beneath the selected repair material.
• 24-inch rod included: Supplied with one approximately 610mm threaded aluminium rod.
• Part of a reusable tool system: Uses the Mole Stand, SpeedNut and Speed Chute, which can then move to the next repair.

Technical Information

HoleMole #5 Technical Data

Size-selection notice: For an opening close to either end of the stated range, verify the complete diameter and seating condition before installation. Large, damaged or structural openings should be reviewed by the responsible designer or engineer.

Applications

Typical Uses for the 241–318mm HoleMole

HoleMole #5 is intended for the largest openings covered by the standard five-size range.

• Major service alterations: Closing large redundant cores after substantial pipework, riser or equipment changes.
• Industrial and utility facilities: Supporting approved repair material in large concrete slab penetrations.
• Data-centre and infrastructure projects: Making good substantial openings while limiting routine access on the level below.
• Large commercial refurbishments: Repairing oversized cores created during phased building-services work.
• Approved wall repairs: Using the Wall Applicator and bendable tabs where vertical installation is included in the project method.

How to Use

How to Install HoleMole #5

1. Measure the entire opening and verify that the clear diameter lies between 241 and 318mm.
2. Check the concrete edge and surrounding slab for damage, then complete the preparation required by the engineered or specified repair system.
3. Attach the supplied threaded rod, fold the HoleMole #5 perimeter sections and carefully lower the large former through the core.
4. Draw the rod upwards until the Mole opens and seats evenly. Inspect its position before placing any repair material.
5. Centre the stand, engage and tighten the SpeedNut, then connect the Speed Chute to control placement into the large opening.
6. Fill in accordance with the material instructions, finish the surface and remove the reusable tools only after the required initial set or cure stage.

Important: Large openings may carry project-specific structural or fire-stopping requirements. HoleMole #5 supplies the former only; it must be used as part of a complete approved repair specification.

FAQs

What is the largest hole covered by HoleMole #5?

HoleMole #5 covers measured core holes up to 12.5 inches, approximately 318mm, with a lower range limit of 9.5 inches or approximately 241mm.

Would HoleMole #5 suit a 300mm core hole?

A correctly measured 300mm opening falls inside the 241–318mm size range. Confirm that the opening is sound and the former seats with the required overlap before filling.

Why are stability ribs used on size #5?

The ribs add stiffness to the larger-diameter galvanised-steel former while it supports the repair material.

What arrives with an individual HoleMole #5?

The pack includes one size #5 Mole and one 24-inch threaded aluminium rod. Application tools and repair material are separate.

Can it be used for fire-stopping a floor opening?

HoleMole is the supporting former, not a certified firestop on its own. Any fire-resistance requirement must be met by a tested or assessed complete system specified for the opening.

Which HoleMole parts are reusable?

The Mole and rod form part of the completed repair. The stand, SpeedNut, Speed Chute and compatible Wall Applicator are reusable tools.

Where is HoleMole #5 available in the UK?

It is supplied by Cable Glands UK to customers nationwide, with technical support from the company’s Manchester team.
