Installers use it daily and the choices are many to achieve the finest installation for our customers. According to information published by the Halex Corporation, until tackstrip was developed in the 1930s, most residential floors were made of hardwood and any carpet that did exist was either loose laid or "turned and tucked" and fastened to the floor with upholstery tacks.

The new innovation of "tackless carpet gripper" revolutionized the carpet industry. Today, this product is commonly referred to as carpet strip, tackstrip, tackless strip, or tackless carpet gripper. Whatever you call it, there are several important factors to consider when selecting carpet strip for a particular type of installation, including: the type and height of the carpet, the width of strip, the type of anchoring nail used, the length of strip, the quality of the wood, the pin height, and whether or not to use aluminum strip.

Powerstretching requires that the installer use the recommended tackstrip to hold the stretch in the carpet and to hold securely at the wall and not allow the tackstrip to pull out of the substrate. Carpet with heavily-latexed backings, rooms exceeding 30-feet in length or width, Berber-type or woven carpet require the use of commercial or Tri-Tack tackstrip or can be double stripped. To avoid injury, the tackstrip pins should never protrude through the face of the carpet to avoid injuries.

  • Install tackstrip with the gully or distance between tackstrip and wall, slightly less than the thickness of the carpet.
  • Cut the tackstrip to follow all room contours, around door casings and wall irregularities.
  • Tackstrip is placed on each tread of the stairs with the pins pointing toward the riser and on each riser, with the pins pointing down toward the tread. The gully shall be slightly less than double the thickness of the carpeting. If spindles are on the stairs, place the tackstrip completely around each side of the spindles.
  • In all areas, secure tackstrip to obtain and maintain the powerstretch; using nails, mechanical fasteners and/or adhesives.
  • The tackstrip pins are to be angled toward the wall.
  • Tackstrip should never be installed across door openings. If tackstrip is installed where carpet abuts to hard surfaces, consider the appearance and safety of doing so.
  • Carpet is NEVER stapled to the tackstrip under any circumstances.
  • On radiant-heated floors, an adhesive-fastening method is recommended. Do not drive nails or screws into conduit or tubing.
  • The use of tackstrip is also acceptable for double-glue installations.


One-Inch Wide

Plywood is one full inch wide. Front and back rows of pins are moved farther apart for extra strength and easier hooking with stiff carpets or thick cushion. Use during residential and commercial installations when extra holding power is desired. Meets the requirements of CRI-104 and CRI-105 for residential carpet installation.

Tri-Tack (Commercial Jr.)

Introduced in the mid-1990s, Tri-Tack is now the fastest growing type of strip sold. Offers a full 3 rows of pins set in a 1-1/4 inch wide plywood strip. This is an economical alternative to double stripping and to full width commercial carpet strip. Provides extra insurance on difficult residential installations. Excellent for use on Berbers. Meets the requirements of CRI-104 and CRI-105 for residential and commercial carpet installation.

Used on difficult installations of any kind. Three rows of pins are spaced equally over a 1-3/4 inch wide strip. Anchoring nails are positioned closer to the wall to prevent strip from lifting during heavy stretching. Use on large installations when maximum holding power is required. Meets the requirements of CRI-104 and CRI-105 for residential and commercial carpet installations.


All types of carpet strip are available in several different pin heights in order to accommodate even the most exacting carpet installation requirements.

Unless otherwise specified, stock qualities are shipped with "E" pin length (approx. 7/32-inch).

C Pin

1/4-inch pin height use for carpets with rough or thick backings where extra penetration is required.

E Pin

7/32-inch pin height used for most carpet installations.

D Pin

3/16-inch pin height for carpets with short, dense pile to avoid pins showing through the carpet face.

J Pin

5/32-inch pin height used with very thin carpet, fine velours and velvets with thin backings.


Aluminum carpet strip is an effective alternative when installing carpet in areas where water damage, termite damage, and other types of damage to plywood carpet strips are risks. It is also a practical solution for high traffic areas such as entryways and doorways where tall pins poke through carpet and pose danger. Shorter than J-pins, aluminum strips' 1/8-inch pins are angled to grip the carpet instead of sticking up through it. Aluminum carpet strip can be installed with any carpet, but is particularly useful with low-pile carpet. Strip is one-inch wide, over 240 pins per 4-foot length. Contains a groove for adhesive beading when nailing is not feasible. Will not rust or rot. Made from 100% high-strength aluminum.
