Keep your cable systems safe and tidy around the roof with the MPC-325. This clip can be used with any type of heat cable from self-regulating to constant wattage to AV or telecommunications. It is designed to work on asphalt shingle roofs ranging in thickness between 1/8”- 3/8”. Need to run cable vertically up a roof? Dealing with a woven shingle valley with no room for standard clips? Want to secure cable tightly to the lip of an exposed dormer flashing? The MPC-325 is a perfect clip to address the improvisational nature of cable installations in the field.
Installations require NO tools and NO nails or screws, greatly decreasing installation time while also eliminating potential liability associated with using traditional nail-on clips. Additionally, the MPC-325 can be easily repositioned or removed without damaging the roofing materials by simply bending up the top arms of the clip.
How it works: There are six robust aluminum barbs on the body of each MPC-325. These barbs embed, or ‘bite’, into the back of the asphalt shingle, creating a semi-permanent anchor that can be used for many years without creating damage when removed. The MPC-325 is a part of the Patented line of the Grip Clip™ family.
“Heat Tape Pro did exactly what I needed it to do. Now I don’t have to worry about water leaking into my house, because I can tell when it’s working by the little light on the end of the cable.”

The MPC-325 uses a patented design with opposing aluminum arms that clamp onto asphalt shingles mechanically. The barbs on the body bite into the body of the shingle, creating a secure hold without nails, screws, or adhesives.
No.
Keep in mind that these are specialty clips and that they shouldn't be used as the primary clip for whole system installations. That's a better job for the grip clip 325. The MPC-325 is used Install cable heat cable in tight areas or where you want the cable to route vertically or in other directions not normally allowed by traditional grip clips.
They’re designed for asphalt shingles 1/8" to 3/8" thick, just like the Grip Clip 325. The difference is their versatility: MPC-325s are ideal for vertical runs, woven shingle valleys, or places like dormers where standard clips may not work as easily.
Not typically. For standard installs, they slide under shingles by hand. If the shingles are stuck down tightly, a putty knife can be used to release the glue strip before inserting the clip.
Not recommended. Once removed, the aluminum loses its ability to grip as firmly. For the best performance, always use new clips when reinstalling a system.
The “325” refers to the clip’s mouth opening, which fits shingles between 1/8" and 3/8" thick. For thicker shingles, use Grip Clip 625 or Grip Clip 875.
They’re made from 5052 aluminum alloy, chosen for its spring strength, corrosion resistance, and durability in extreme freeze–thaw conditions.
Yes, they create a semi-permanent anchor that can be used for many years. The aluminum barbs provide excellent holding power without penetrating your roof material.
The MPC-325 is the most versatile clip in the Grip Clip family. It’s particularly useful for vertical runs, woven valleys, or tight roof details where standard Grip Clips don’t fit as neatly. For straight eaves and typical zig-zag patterns, the Grip Clip 325 is the best choice. Many contractors keep both on hand to cover every scenario.
Each MPC-325 provides at least 25 pounds of pull strength, giving installers confidence that cables will stay put under heavy snow and ice loads.
Many years. The 5052 aluminum alloy won’t rust, and the clips are built to withstand winter conditions year after year.

These are truly multi-purpose clips. You can use them with any type of heat cable, from self-regulating to constant wattage and even AV or telecommunications cables. They're designed to handle the improvisational nature of real-world cable installations. People even use them for holiday lighting.
PipeFreezePRO comes with one or more 30ft rolls of high-quality fiberglass tape, but you can use any tape with a temperature rating of 150º F and above. Self-adhesive aluminum foil tape can be used but avoid standard tapes, including electrical tape and duct tape because they lose their adhesion when exposed to heat. Remember, it’s imperative to cover the pipe/heat tape assembly with pipe insulation (1/2″ minimum thickness). Think four easy steps: 1) cable on pipe, 2) tape on cable, 3) insulation on pipe/cable and 4) tape on insulation.
Pipe Freeze PRO can be overlapped during installation. This is a fundamental advantage of self-regulating heat cable over cheap, constant wattage cable found in hardware stores is that it can be overlapped without risk of shorting out or catching fire. So yes, overlap away!
The amount of heat cable needed for pipe freeze prevention is determined by a couple of simple factors including: Length of pipe, diameter of pipe, distance to power supply and number of valves.
Most of the time, we do not recommend a spiral cable application because it’s simply not necessary. It requires 3x the cable to do the same job.
Therefore, simply use a straight, single run of cable affixed to the bottom of the pipe (think 6 o’clock position) using the provided fiberglass installation tape. Next, add 1 foot of cable for every valve because you will be wrapping the valve with cable. For pipes less than 1″ in diameter, a single cable run is sufficient. For larger pipes, two cable runs are recommended. Keep in mind that plastic pipes are less thermally conductive so you may choose to use two cable runs on larger plastic pipes to be safe. Finally, if your outlet isn’t close to the pipe you are treating, factor in enough heat cable to reach your outlet (Pipe Freeze PRO does come with a 36″ power cord).
Finally, you must install insulation on your pipe and heat cable assembly in order for the system to operate effectively. See instructions for further details.
The cable can be exposed to wetness but the thermostat must stay dry to function properly. Use Pipe Freeze PRO for pipe freeze prevention applications only.
Consider using Heat Tape Pro inside of open drain pipes as that cable is rated for use in wet areas.

Pipe Freeze Pro’s integrated thermostat turns power on and off automatically to the cable to save electricity. The thermostat is the lump located between the power cord and the heat cable. The thermostat triggers the cable to turn on at 37ºF and off at 50ºF, with a sensitivity range of +/- 4ºF. It’s a great feature that makes Pipe Freeze Pro unique among heat cables on the market.
Yes and no. The cable is approved for exposure to wet conditions but you should keep the thermostat dry for proper operation.
No. The thermostat need only be exposed to cold air. It does not hurt to have the thermostat attached to the pipe but it is not necessary. If you choose to attach it to the pipe keep in mind that the thermostat should not be covered with insulation.
No. You want the thermostat to react to the cold environment so it triggers the Pipe Freeze Pro to turn on.
