Blackthorn’s Magnetic Step Pin Assembly forms the holes necessary for installation of manhole steps.
Mounts magnetically to the form (also available with nail holes for use with non-magnetic forms).
Eliminates need to drill step holes after the structure has cured, saving you time & money!
Available for both FLAT WALL & ROUND WALL structures.
Using wire to tie hole-formers into the rebar cage can be laborious and unreliable – hole-formers may float during the production process.
Coil or NC thread bolts will hold the hole-former securely in place, but drilling the necessary holes for the bolts will permanently damage your form walls.
Magnets are the easiest and most reliable way to mount hole-formers to steel forms – no more floating hole-formers or “Swiss cheese” forms!
Hole-Former Magnets are interchangeable – simply use more magnets for larger hole-formers (SPEC SHEET)
MAGNETIC RECESS MEMBERS & INSERTS
Blackthorn offers Magnetic Recess Members, Magnetic Profile Plates, and Magnetic Inserts for a variety of different lift systems, anchor types, capacities, and recess member shapes/designs.
Select your lift system below to view options.
FORM SUPPORT MAGNETS
Designed to support side rails and/or blockouts in steel forms.
Button Magnets are easily attached to steel forms by engaging the button. When finished, remove the Button Magnet by simply disengaging the button.
Lifting Handles are available to aid in disengaging the button.
Loaf Magnets are designed to support side rails and otherwise support forms.
BULKHEAD / RAIL MAGNETS
Bulkhead Magnets are an more economical alternative to other magnetic form support options.
Can be CUSTOM MADE to your specific application (most common sizes are 3″x3″ & 3″x6″)
Available with nail holes for wooden/non-magnetic forms.
COIL THREAD PROTECTORS & FERRULE LOCATORS
Magnetic Coil Thread Protectors feature a threaded steel core with a tapered magnetic base for easy removal with a 1/2″ drive tool.
Coil Thread Protectors with nail holes (for wooden/non-magnetic forms) are also available.
Magnetic Ferrule Locators are used to fix ferrule / NC thread inserts into forms. They feature a threaded steel core with a tapered magnetic base for easy removal with a 1/2″ drive tool.
The Unistrut Magnet is inserted into a Unistrut channel, allowing it to be effortlessly attached to a steel form.
Its flexible urethane “wings” allow it to fit multiple channel profiles.
Blackthorn’s Styrofoam Mounting Magnets enable quick and easy attachment of foam hole-formers to steel molds.
Simply push the magnet into the foam hole-former, place against your mold, and the foam hole-former will be securely held in place for the duration of the pour.
EASY and RELIABLE – no more tying in foam hole-formers with wire and no more floating foam hole-formers.
Foam Mounting Magnets work best with small to medium size holes. MAGNETIC STEP PIN ASSEMBLIES can be used to mount large foam hole-formers.
MAGNETIC KEYWAY / BAFFLE SLOT FORMERS
These blockouts can be positioned on form walls to form keyway / baffle slots.
Made of durable, solid urethane with embedded heavy-duty magnets and flat “butt joints” on the small sides, which allow multiple blockouts to be stacked together to create any desired slot length.
We have several existing urethane molds for various sizes and can inexpensively create new molds to meet your needs.
Keyway/Baffle Slot Formers can also be made out of aluminum by custom request.
MAGNETIC COLD JOINT / REBAR HOLE-FORMERS
The Cold Joint/Rebar Hole-Former creates the necessary holes for rebar placement for secondary pours.
No more hand-drilling rebar holes!
CUSTOM MADE to your specifications – although, standard sizes are available (most common size is a 7/8″ tapering to 1-1/8″ x 4″ long Steel Pin with a 3.5″ long x 3.5″ wide x 3/8″ thick magnetic base plate).
FORM LINER ACCESSORIES & WOOD MAGNET
Wood Magnets can be screwed onto wooden forms to suspend the steel embedded plates on the top of wall panels, among other uses.
Can also be used to attach a wood-backed form liner to a steel form, or for many other magnetic-to-non-magnetic attachments.
FORM LINER MAGNET
Allows for magnetic attachment of form liners to steel forms to ensure accurate and secure placement.
VICTORY BEAR CLIP MAGNET
Allows for magnetic attachment of Victory Bear rustication strips to steel forms.
Quick, easy, and secure attachment with no need for caulk!
