A climbing wall is an artificially constructed wall with manufactured grips for the hands and feet. Most walls are located indoors, and climbing on such walls is termed indoor climbing. Some walls are brick or wooden constructions, but on most modern walls, the material most often used is a thick multiplex board with holes drilled into it. Recently, manufactured steel and aluminum have also been used. The wall may have places to attach belay ropes, but may also be used to practice lead climbing or bouldering.
Drywall is a panel made of calcium sulfate dihydrate (gypsum), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber ; plasticizer, foaming agent; and additives that can reduce mildew, flammability, and water absorption.
A drill bit is a cutting tool used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.
An eraser is an article of stationery that is used for removing marks from paper or skin. Erasers have a rubbery consistency and come in a variety of shapes, sizes, and colors. Some pencils have an eraser on one end. Erasers can come in various shapes and colors. Less expensive erasers are made from synthetic rubber and synthetic soy-based gum, but more expensive or specialized erasers are made from vinyl, plastic, or gum-like materials.

Plasterwork is construction or ornamentation done with plaster, such as a layer of plaster on an interior or exterior wall structure, or plaster decorative moldings on ceilings or walls. This is also sometimes called pargeting. The process of creating plasterwork, called plastering or rendering, has been used in building construction for centuries. For the art history of three-dimensional plaster, see stucco.
Artur Fischer was a German inventor. He is best known for inventing an expanding plastic version of the wall plug.
Lime mortar or torching is a masonry mortar composed of lime and an aggregate such as sand, mixed with water. It is one of the oldest known types of mortar, used in ancient Rome and Greece, when it largely replaced the clay and gypsum mortars common to ancient Egyptian construction.
A pattress or pattress box or fitting box is the container for the space behind electrical fittings such as power outlet sockets, light switches, or fixed light fixtures. Pattresses may be designed for either surface mounting or for embedding in the wall or skirting board. Some electricians use the term "pattress box" to describe a surface-mounted box, although simply the term "pattress" suffices. The term "flush box" is used for a mounting box that goes inside the wall, although some use the term "wall box". Boxes for installation within timber/plasterboard walls are usually called "cavity boxes" or "plasterboard boxes". A ceiling-mounted pattress is referred to as a "ceiling pattress" or "ceiling box". British English speakers also tend to say "pattress box" instead of just "pattress". Pattress is alternatively spelt "patress" and Wiktionary lists both spellings. The word "pattress", despite being attested from the late 19th century, is still rarely found in dictionaries. It is etymologically derived from pateras. The term is not used by electricians in the United States.
Stone veneer is a thin layer of any stone used as decorative facing material that is not meant to be load bearing. Stone cladding is a stone veneer, or simulated stone, applied to a building or other structure made of a material other than stone. Stone cladding is sometimes applied to concrete and steel buildings as part of their original architectural design.
The Rawlplug Group is a company involved in the production of fixings, fasteners, and other tools.
Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences.
Anchor bolts are used to connect structural and non-structural elements to concrete. The connection can be made by a variety of different components: anchor bolts, steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces.
A threaded insert, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole. They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece thereby eliminating a machining operation, or simplify changeover from unified to metric threads or vice versa.
A climbing hold is a shaped grip that is usually attached to a climbing wall so that climbers can grab or step on it. On most walls, climbing holds are arranged in paths called routes, by specially trained route setters. Climbing holds come in a large array of sizes and shapes to provide different levels of challenge to a climber. Holds are either bolted to a wall via hex-head bolts and existing t-nuts or they are screwed on with several small screws. In extreme cases, concrete anchors may be used.
John Joseph Rawlings was a British mechanical engineer and inventor of the wall plug, also known from his name as the rawlplug. He was the founder of the Rawlplug manufacturing company.
A molly or molly bolt is a type of screw fastener that fastens objects to plaster or gypsum board hollow walls by providing an anchor to be lodged inside a hole and expanded once in position. Larger sizes permit reasonably heavy objects, such as shelving, flatscreen-TV mounts or central-heating radiators, to be attached to drywall in locations where there is no stud behind the drywall. For heavy objects, multiple molly bolts may be required.
Fischerwerke GmbH & Co. KG is a family-owned German multinational manufacturer, best known for its fastening products for the construction and DIY industry. The company also has divisions in the Automotive, Toy, and Consulting industries. Fischer is considered to be a typical example of a large-sized mittelstand company. The name of the firm is not written with a capital 'f', which is an oddity especially in a German context where all nouns are generally written with an initial capital.
A drywall anchor, also known as a wall anchor, is an insert that, combined with the appropriate screw, can create a strong mount anywhere on a drywall panel or similar hollow wall. A drywall anchor goes between the screw and the drywall, gripping the drywall much more effectively than a screw would. Some have toggle arms that either drop behind the wall or expand within the cavity. Others include wide threads that carve out grooves in the wall for traction. All drywall anchors are designed to create a strong mount point by distributing the applied load over an increased surface area.
A furniture screw can refer to any type of screw used on furniture. Different types of screws have different uses in furniture.
