Picture hanger_ Safety Hook Series

Picture Hanger　Safety Hook Series

* Rail mounting screws are not included because the substrate is different. Please select screws that match the wall material.

Recommended: ø3.5 to ø4.0, length 30 mm or more

*Since the substrate position is different, we do not drill holes in the rails. Please check the substrate position before drilling.

Recommendation: Drill holes of 4.5mm to 5.0mm with an electric drill, etc.

What is the difference between the safety hook series and general hanger hooks?

Picture hangers are mainly used to hang frames and panels.

Manufacturers all over the world are selling the design (and cost, of course...), and they are used mainly in museums.

The differentiation of picture hanger itself is directly focused on the design.

The biggest difference between our picture hanger safety hook series and general hanger hooks is that our picture hanger safety hook series has a thinner wire diameter, which allows you to hang heavy objects safely.

The reason is that the gripping mechanism of the hanger hook is different from that of general hanger hooks.


	Ultima grip ：Shoe type grip		Other grip ：Bearing grip
Features	Shoe type grips (surface fixation) distribute the load by clamping the wire between two surfaces, thereby reducing the load on the wire. The original strength of the wire is maintained. The shoe-type grip is a proprietary technology of Ultima.		Bearing type grips (point fixation) have less braking force because the force is concentrated at a single point, and the wire is easily damaged. The wire is easily damaged.
Safety	〇	High strength and high safety ratio Utilized in industrial products	△	Often utilized in display and interior design
Strength	〇	Surface contact Strong grip, especially resistant to vibration *1	×	Point contact Grip strength is low. Weak against shock and vibration *2
Release	×	Grip force is strong. Difficult to release by hand (finger) *3	〇	Grip force is low Easy to release by hand (finger)
Burden on wire	〇	Surface fixation Less burden due to distributed load Less damage and indentation such as strand breakage and waviness	×	Point fixation Load is concentrated, so there is a heavy burden. Damage and indentation such as strand breakage and waviness are inevitable. Wire maintenance is necessary
Production	〇	Original design, not an off-the-shelf product Other companies cannot easily manufacture (difficult to manufacture equivalent products)	×	Uses off-the-shelf bearings Easy to manufacture

*1：90% to 100% of JIS standard wire breaking load of 170kg based on SUS304φ1.5mm (7×7) wire test values.

*2：50-70% of 170kg of JIS standard wire breaking load based on SUS304φ1.5mm (7×7) wire test value.

*3：Hybrid mechanism (pat.p) is also available to solve the disadvantage of difficulty in releasing the gripping force.

Basic Grip Operation

Grip Strength

Wire	Maximum Static Load Value	Allowable Load Value
φ1.5	1670N～1880N (170kg～192kg)	490N～640N (50kg～65kg or less)

＊ The maximum static load value is the maximum value when a stainless wire (7 x 7) is used for the grip in a stationary state and pulled until the wire breaks (when it breaks).

＊ The allowable load is calculated with a safety factor of approximately 1/3 of the maximum static load value, but the safety factor should be considered depending on the conditions of use.

＊ The maximum static load value varies depending on the type of wire used. Please contact us if you have any questions.

Comparison of allowable load value by wire diameter

Wire	ULTIMA grip (shoe type grip)	Other grip (bearing type grip)
φ1.5　＊1	50kg～65kg	30kg

＊ The allowable load is calculated with a safety factor of approximately 1/3 of the maximum static load value, but the safety factor should be considered depending on the operating conditions.

＊1 Allowable load differs depending on the type of hanger hook.

For general grips, the wire diameter equivalent to an allowable load of 65 kg is φ2.5.

In contrast, Ultima grips can be used with φ1.5 wire diameters, which is most commonly used for hanging exhibits.

In fact, the grips themselves are often hidden behind the frames, so it is the wire diameter that really stands out.

With thinner wire, heavy objects can be hung strongly, beautifully, and safely in a compact body.

This is the Picture Hanger Safety Hook series.　

Features of Safety Hook Series

Features
With its compact mechanism and high strength, it is applied in fields where safety is required, such as picture hangers. Simple one-touch position adjustment for hanging paintings, frames, and panels. One-touch locking and adjusting function. Locked by simply inserting the wire and unlocked by operating the pin, taking advantage of its impact-resistant structure. Easy to operate for smooth level movement.
Attention
Rail mounting screws are not included because the substrate is different. Please select screws that match the wall material. Recommended: ø3.5 to ø4.0, length 30 mm or more Since the substrate position is different, we do not drill holes in the rails. Please check the substrate position before drilling. Recommendation: Drill holes of 4.5mm to 5.0mm with an electric drill, etc. Screws for rail installation are usually recommended to be set @450mm for L=900. When installing the rail, check the location of the substrate and be sure to install the rail in a location where the screws are secure. Please note that the strength of the screws will affect the safety strength of the rail. Special metal fittings may be required depending on the mounting location. Do not apply paint or oil to the grips or wires. Mounting method varies depending on the wall material. We assume no responsibility for any damage or accident caused by incorrect installation.
